Art advancing science at the nanoscale
Like many other scientists, Don Ingber, M.D., Ph.D., the Founding Director of the Wyss Institute, is concerned that non-scientists have become skeptical and even fearful of his field at a time when technology can offer solutions ...
Two-dimensional materials gets a new theory for control of properties
Desirable properties including increased electrical conductivity, improved mechanical properties, or magnetism for memory storage or information processing may be possible because of a theoretical method to control grain ...
New graphene nano-ribbons lend sensors unprecedented sensitivity
Pinning DNA-sized ribbons of carbon to a gas sensor can boost its sensitivity far better than any other known carbon material, says a new study from the University of Nebraska-Lincoln.
Chemical treatment improves quantum dot lasers
One of the secrets to making tiny laser devices such as opthalmic surgery scalpels work even more efficiently is the use of tiny semiconductor particles, called quantum dots. In new research at Los Alamos National Laboratory's ...
Vibrating nanoparticles interact: Placing nanodisks in groups can change their vibrational frequencies
Like a tuning fork struck with a mallet, tiny gold nanodisks can be made to vibrate at resonant frequencies when struck by light. In new research, Rice University researchers showed they can selectively alter those vibrational ...
Researchers advance characterization, purification of nanotube wires and films
To make continuous, strong and conductive carbon nanotube fibers, it's best to start with long nanotubes, according to scientists at Rice University.
Researchers watch in real time as fat-encased drug nanoparticles invade skin cells
Some anti-cancer drugs are encapsulated to allow gradual release, spreading their effect over a longer time. For example, one formulation of the chemotherapy doxorubicin (the FDA-approved drug Doxil) encloses molecules of ...
Can nanotechnology heal scar tissue?
Think scars last a lifetime? Think again.
The big problem of global food production has a very tiny solution
The answer to the growing, worldwide food production problem may have a tiny solution—nanoparticles, which are being explored as both fertilizers and fungicides for crops.
