Knotting Nanoropes
Biomimetic systems that are composed
of rigid polymers or filaments and crosslinking molecules
can be used to assemble Nanoropes, filament networks
and bundles. The bundles represent `nanoropes' and
exhibit material properties that are primarily determined
by the number of plaited filaments.

Nanoworld sets the Limit to "Small"
Scientist at University
of Arizona stating 25 Nanometer as the limit to which
object can be shrinked. This is mainly due to existence
of Vander waal's force existing between atom and molecules
of any substance.

Smart Nanoprobes to locate the Diseases.
Quantum Dots
are programmed with the technique called 'Quenching'
to glow in presence of Enzyme Activity. Researchers
from Rice University Center for Biological and Environmental
Nanotechnology (CBEN) have developed Smart NanoProbes
hundreds of times smaller than a human cell that lights
up only when activated by specific proteases (Enzymes
that degrade Proteins). Such Enzymes degrading proteins
are common in diseases like cancer and atherosclerosis

Smart Bionanotubes Developed
"Smart" bionanotubes: Lipid
protein nanotubes made of microtuble protein
(made of tubulin protein subunits shown
as red-blue-yellow-green objects) that
is coated by a lipid bilayer (drawn with yellow
tails and green and white spherical heads)
which in turn is coated by tubulin protein
rings or spirals. By controlling the relative
amount of lipid and protein it is possible
to switch between two states of nanotubes
with either open ends (shown in the center) or closed
ends with lipid caps (shown on the left),
a process which forms the basis for controlled
chemical and drug encapsulation and release.

and engineering products to nanotechnology community
annouced their plans to open a nanotechnology centers
in Bangalore, India. Facility will be equipped with
Veeco's latest AFM's (Atomic Force Microscope's),
Scanning Tunneling Microscope (SPM) alongwith other
advanced nanotechnology products. Bangalore Facility
will be managed with local scientist and engineers
in the nanotechnology fields. This Nanotechnology
facility will be associated with Jawaharlal Nehru
Center for Advanced Scientific Research (JNCASR).

Carbon Nanotubes for fastest communication of computer and mobile networks
Nanotechnology Scientist at
University of California Irvine demonstrated the fastest
propagation of Electrical signals with the help of
Carbon Nanotubes. Nanotubes can achieve speed as fast
as 10 GHz which is much faster than traditional channels
of Aluminium or copper wires. This breakthrough will
lead to more faster and efficient network for computers,
cell phone systems and wireless networks.
