Euler buckling in red blood cells: An optically driven biological
micromotor
Authors: A. Ghosh, S. Sinha, J. A. Dharmadhikari, S. Roy, A. K.
Dharmadhikari, J. Samuel, S. Sharma, D. Mathur
Subj-class: Biological Physics; Optics; Soft Condensed Matter

We report the observation of an optically driven micromotor of
biological origin. A single red blood cell (RBC) folds when placed
in an optical trap. The folded RBC is birefringent and rotates in
circularly polarized light. Optical forces permit a high degree of
control over the speed and direction of rotation of such a
micromotor. This cellular micromotor has potential applications in
micromanipulation, possibly like an "optical screwdriver" to apply
torques at the micron scale. A simple theoretical model captures the
main observed features and makes predictions that are successfully
tested.

President's advisers to consider export controls on nanotech. A panel that
advises President Bush on export issues will explore whether nanotechnology
needs regulating. The committee, which will be assembled early this year, is
expected to review other nations' nanotechnology capabilities, their
competitiveness and nanotechnology's impact on national security. Lawyers who
specialize in export law recommend nanotechnology companies follow developments
to ensure they comply if regulations eventually are put in place. The scope
could range from restrictions on international trade to rules on staffing
foreign nationals. (Smalltimes 2/3/05)

St. Louis, MO, January 17, 2005 - Elsevier, the world-leading scientific and
medical publisher, announces plans to launch the world's first peer-reviewed
journal devoted to nanomedicine - the emerging science of using molecular
machines to treat human disease. Nanomedicine: Nanotechnology, Biology, and
Medicine, the official publication of the American Academy of Nanomedicine, will
be published quarterly, with the first issue to appear in March 2005. (Elsevier)

Friction at the nano-scale. Nanomachines will depend on our knowledge of
friction, heat transfer and energy dissipation at the atomic level for their
very survival. In the scramble to revolutionize the world with nanotechnology we
must not ignore friction. Nano-scale devices based on moving molecular
components have the potential to radically alter technologies such as energy
storage, drug delivery, computing, communications and chemical manufacture. But
getting these devices from the laboratory to the marketplace is far from
guaranteed. (Physicsweb Feb. 05)

Nano's road to the future. 5-year-old National Nanotechnology Initiative keeps
U.S. efforts on course...for now. In January 2000, much of the public got its
first taste of nanotechnology from President Clinton...By internal and external
accounts, the initiative has been successful, albeit a work in progress. It is
at or ahead of some goals. For instance, recent lab advances suggest that the
ability to not only detect but also treat certain types of cancer in their first
year of occurrence is well before the original 20-year timeframe. Globally, the
NNI has inspired or at least encouraged 40 similar programs. Most importantly,
it has fostered true collaboration among the 22 participating government
agencies, something historically turf-conscious career civil servants say is a
major achievement. But challenges loom. Washington has entered a time of
budgetary belt-tightening, just as the government's nano leaders say more money
is needed to move basic research into application development. Experts say those
efforts require a stronger link between government and industry,...(Smalltimes

Nanotechnology and the FDA. The US Food and Drug Administration regulates a wide
range of products, including foods, cosmetics, drugs, devices, and veterinary
products, some of which may utilize nanotechnology or contain nanomaterials. The
FDA defines "nanotechnology" as research and technology or development of
products regulated by FDA that involve all of the following...

Scientists Find Evidence Of Electrical Charging Of Nanocatalysts. Researchers at
the Georgia Institute of Technology and Technical University Munch have
discovered evidence of a phenomenon that may lead to drastically lowering the
cost of manufacturing of materials from plastics to fertilizers. Studying
nano-sized clusters of gold on a magnesium oxide surface, scientists found
direct evidence for electrical charging of a nano-sized catalyst. This is an
important factor in increasing the rate of chemical reactions. The research will
appear in the 21 January, 2005, issue of the journal Science, published by the
AAAS, the science society, the world's largest general scientific organization.

Filling A Fullerene. Japanese group uses organic synthesis to make milligrams of
H2-filled C60. Using organic synthesis as a scalpel and stitches, Japanese
researchers have performed "molecular surgery" on a buckyball. A group at Kyoto
University creates an opening in the molecule, inserts H2 into the cavity, and
then, in just four steps, closes up the C60 framework to construct the
endohedral fullerene H2@C60 [Science, 307, 238 (2005)]. (C&E 1/17/05)

Materials potpourri. Meeting spotlights latest advances in sensors,
biomaterials, nanostructures, and art conservation. Although most Bostonians
returning to work after the Thanksgiving holiday weren't aware of it, Boston
Mayor Thomas M. Menino proclaimed Monday, Nov. 29, 2004--the first day of the
Materials Research Society's annual fall meeting--to be the first-ever Materials
Science Day in Boston. As Menino noted in a proclamation marking the occasion,
MRS "has met in Boston every fall for 27 years and draws more than 5,000
international attendees and exhibitors." This year's MRS conferees braved the
cold weather to absorb more than 2,500 talks and nearly 1,700 poster
presentations. With five full days of symposia to occupy them, many attendees
saw little need to desert the warmth of the Hynes Convention Center and its
adjoining hotel and shopping mall complex, unless it was to attend the "Strange
Matter" exhibit (C&EN, Jan. 12, 2004, page 40) held in conjunction with the
meeting at the Boston Museum of Science. (C&E news 2/3/05)

Carbon Nanotechnologies Inc. Announces Availability of Double-Wall Carbon
Nanotubes. Carbon Nanotechnologies Inc. (CNI) announced today that it has
expanded its pilot plant capability to provide double-wall carbon nanotubes to
the market. Double-wall carbon nanotubes behave similarly to single-wall carbon
nanotubes but have unique property characteristics for some applications. The
technology to produce double-wall carbon nanotubes is part of the intellectual
property developed by Dr. Richard Smalley and licensed exclusively to CNI by
Rice University in 2001. "Even though single-wall carbon nanotubes have become
somewhat of a gold standard product, the properties of double-wall carbon
nanotubes can make them very interesting for certain applications," said Rick
Smalley, chairman of CNI and University Professor at Rice University.

Edventure Museum exhibit explores nano-technology. A new exhibit at Edventure
Children's Museum is letting kids explore a world too small to see. "It's a Nano
World" teaches kids about a nanometer, which is one billionth of a meter,
smaller than one strand of hair. With the exhibit, children are able to measure
themselves in nanometers, see things up close and personal, sort cells and play
inside a drop of blood.

Paint Based on Quantum Dots has Potential to Assist Antiterrorism and Cancer
Detection. Night vision technology could become extremely precise thanks to an
inexpensive water-based material capable of boosting particles of light in the
infrared spectrum, say University of Toronto researchers. The material has the
potential to enhance infrared images tenfold by coating lenses with a film a
10th of a millimetre thick and powering the material with a laser. (Azonano

Nanotech takes aim at transistors. US scientists have made nano-scale devices
they claim could one day replace current transistor technology. The tiny
devices, "crossbar latches", are made up of a combination of crossed-over
platinum wires with steric acid molecules set at their junctions. The Hewlett
Packard researchers said they could potentially do a better job than present
transistors, dramatically improving the performance of computers. The HP team
reports its findings in the Journal of Applied Physics. (BBC 2/1/05)

Controlling guests in nanocapsules. "A detailed understanding of the interplay
and relative orientations of the constituent guest molecules has, until now,
been restricted to a few instances of limited complexity," note chemistry
professor Jerry L. Atwood and coworkers at the University of Missouri, Columbia,
in a recent paper [Angew. Chem. Int. Ed., 43,5263 (2004)]. The paper describes
two important advances relating to nanocapsules with interior volumes in the
1,200?1,500-?3 range, according to Atwood. "First, we show that it is possible
to order the guests on the interior of our large free-standing capsules," he
says. "Second, and most remarkably, we show that these large capsules
communicate with each other, at least in the solid state and probably in
solution, by the formation of intercapsule hydrogen bonds. This communication in
turn leads to a completely different ordering of the guests within the
capsules." (C&Enews 2/3/05)

Test could detect Alzheimer's earlier. A highly sensitive new test could lead to
a different way to diagnose people with Alzheimer's disease, possibly helping
find the illness in its early stages when there might be time for
treatment...Test measures proteins in spinal fluid
Many companies have experimental therapies, he said, "But those therapeutics
aren't very good if you can't definitively diagnose and follow a disease,"
explained Mirkin, a lead researcher - along with William L. Klein - on a team
that developed the new test, which can detect small amounts of proteins in
spinal fluid. The team's findings are reported in Tuesday's issue of Proceedings
of the National Academy of Science. (MSNBC 2/1/05)

Nanotubes Crank Out Hydrogen. Pure hydrogen fuel is non-polluting. Current
methods of extracting hydrogen, however, use energy derived from sources that
pollute. Finding ways to use the sun's energy to split water to extract hydrogen
would make for a truly clean energy source. Several research efforts are using
materials engineered at the molecular scale to tap the sun as an energy source
to extract hydrogen from water. Researchers from Pennsylvania State University
have constructed a material made from titanium dioxide nanotubes that is 97
percent efficient at harvesting the ultraviolet portion of the sun's light and
6.8 percent efficient at extracting hydrogen from water. (Fuel Cell Today

Nanotechnology Detects Human DNA Mutations. Researchers at Nanosphere, Inc. have
reported unprecedented benefits in the company's technology for the medical
analysis of human DNA. Nanosphere's nanoparticle-based technology allows for
rapid, highly-sensitive and specific Single Nucleotide Polymorphism (SNP)
genotyping, which is the direct detection of a particular gene and the extent to
which it is normal or mutated. (Azonano 1/26/05)

Dear Mohammad Moradi:

What can you tell us about nanotechnology in Iran?

How many Iranian scientists would you say are working in the field?

Is there an Iranian view of nanotechnology?  Is it primarily seen as a
source of national and military power in the future, or as a way to solve
human problems such as disease, poverty and hunger, environmental and
energy problems?  Is it a further development of high technology which
will make the rich countries yet more powerful while leaving behind the
developing world, or is it an opportunity for Iran to leap ahead?

Peace (seriously),
Mark

Dear mark gubrad
I know you as an active member of nanotech yahoogroup,
and thank you for attention to this male.
Nanotechnology in Iran goes ahead totally from 4 years
ago. before that there was no governmental support and
some scientists individually have done some projects
on the subject. Although there are some active
laboratories working, but most of research papers was
in the field of computational nanotechnology.
well-known pioneers in Iran now are concentrating on
bionanotechnology to make drug delivery systems and
generally health care. We in RNT corp. work in four
research groups related to oil industry, NEMS, MBB,
and their simulations. In some of them we are just in
first steps but in oil industry MBBs a plan has been
done since 2 years ago.
I have more to say about nano in Iran if necessary.
I look forward to hear your suggestions.
best wishes

I suspect that he, if he answered this directly, would say that the people of
Iran are very progressive and egalitarian, despite all the rhetoric we hear
about their government. There's quite a democratic movement there, as well as
(unfortunately) a socialist movement. They're not all a bunch of militaristic
goons.

The biggest thing holding the third world nations back is their economic
structure. Most of them have very socialist governments, and even the
"reforms" pushed on them by the West tend to be market socialism, not the
kind of economic freedom they need to catch up.

What we need is for people to study nanotech, biotech, and artificial
intelligence simultaneously. One of the great curses of modern academia is
the push for specialization, retarding progress by creating a lot of
duplicated effort.

Is there a reason why nobody's working on glueing carbon nanotubes, instead
of all this complicated welding and stuff that nobody's solved yet?

it is where the Internet began. I'm sure it also has
biotech; the nanotech division is formed out of a

Vulvox Nano/Biotechnology Corporation has invented CMOS type nanotransistors 5nm
on a side that operate the same way as much bigger silicon CMOS logic circuitry.
It is probable that the latch circuits will be shown to display something called
"latch up" that is a big problem with certain silicon devices. The
unconventional pulse scheme that switches nor gates and other elements of that
network will probably cause unknown problems similar latch up since that
archetecture is unknown. Our circuitry uses smaller versions of CMOS logic and
all of the bugs have been worked out already. We can arrange them in three
dimensions to densities of 50 trillion transistors per square centimeter.

Subject: Liquid carbon plays role in nanotube formation

Researchers have discovered that the formation of multiwalled carbon
nanotubes in a pure carbon arc involves liquid carbon. They believe
that the nanotubes formed by homogeneous nucleation inside droplets of
the liquid.
Liquid carbon plays role in nanotube formation: carbon nanotubes
Carbon nanotubes

"We were doing research on the electrical transport properties of
carbon nanotubes when we noticed that the nanotubes had these little
beads that looked like liquid drops on them," said Walt de Heer of the
Georgia Institute of Technology. "We hope our results will open up the
whole question of nanotube formation again."

De Heer worked with colleagues from the Georgia Institute of
Technology, US; University of Montpellier, France; CNRS-LEPES, France;
University of Illinois at Urbana-Champaign, US; Laboratório Nacional
de Luz Sincrotron, Brazil; and the University Estadual de Campinas,
Brazil.

The scientists grew the nanotubes by creating a carbon arc between two
carbon electrodes in a helium atmosphere. At higher helium pressures,
the process produced carbon nanotubes. At low pressures of helium, the
arc emitted fullerenes (buckyballs). The scientists say that unlike
catalytically produced multiwalled nanotubes, pure carbon-arc-produced
nanotubes are essentially defect-free.

The reaction formed carbon columns about 1 mm long and 0.1 mm wide.
Inside the columns were randomly aligned multi-walled carbon
nanotubes, around 3-20 nm in diameter and several micrometres long,
and graphitic nanoparticles. On the surface of the columns was a layer
around 100 nm thick, with nanotubes protruding from the surface. These
nanotubes often had beads of amorphous carbon around them.

"We asked the question, if the beads were once liquid carbon and the
nanotubes they are attached to are also carbon, why didn't the liquid
carbon dissolve the nanotube?," said de Heer. "The answer is that the
liquid must have been a glass at a lower temperature than the nanotube."

The scientists reckon that electron bombardment from the cathode
heated up the carbon anode, causing the surface to liquefy in places
and eject liquid-carbon globules. The surface of the globule then
cooled fast, causing it to glassify. The interior cooled more slowly,
however, so that the liquid carbon supercooled and carbon crystals
nucleated and grew into nanotubes and graphitic nanoparticles.
Capillary forces resulted in the glass coating beading on the nanotubes.

The researchers, who reported their work in Science, reckon that the
radial temperature gradient in the drop during cooling encouraged the
carbon crystals to grow into nanotubes.

hi

  can i know, how will u attach the capsule that cures brain tumor to the C60.

hey there ppl,


i was goin thru this article some time back......the article goes on
like this....The C60 ( buckminster fullerene) has the ability to pass
thru all the tissues muscles etc.. up to the brain....so....if thats
the
case.....any drug which is capable of curing diseases like Brain
tumour
can be attached to the C60 molecule....which can cure the
disease....and restore the health.....Is my thought correct....I wish
all the members participate in the discussion and express their views
on the topic.....
