Electronically controlled drug delivery from graphene nanocomposites

Potential side effects of many of today's therapeutic drugs can be downright frightening - just listen carefully to a drug commercial on TV. These effects often occur when a drug is active throughout the body, not just where and when it is needed. But scientists are reporting progress on a new tailored approach to deliver medicine in a much more targeted way.

Nanotechnology-enabled smartphone-based mercury testing

A team of researchers from UCLA has developed a smartphone attachment and application to test water for the presence of mercury, a toxic heavy metal. The scientists created an integrated opto-mechanical attachment to the built-in camera module of a smart-phone to digitally quantify mercury concentration using a plasmonic gold nanoparticle and aptamer based colorimetric transmission assay that is implemented in disposable test tubes.

Inner workings of a cellular nanomotor revealed

Our cells produce thousands of proteins but more than one-third of these proteins can fulfill their function only after migrating to the outside of the cell. While it is known that protein migration occurs with the help of various 'nanomotors' that push proteins out of the cell, little is known about their precise mechanical functioning. New research reveals the inner workings of one such nanomotor, called SecA, with new clarity.

Off-the-shelf materials lead to self-healing polymers (w/video)

Look out, super glue and paint thinner. Thanks to new dynamic materials developed at the University of Illinois, removable paint and self-healing plastics soon could be household products. A slight tweak in chemistry to elastic materials made of polyurea, one of the most widely used classes of polymers in consumer goods, yields materials that bond back together on a molecular level without the need for other chemicals or adhesives.

Cellular surgeons: The new era of nanomedicine (w/video)

Pills the size of molecules to seek and destroy tumors. Miniscule robots performing surgery inside patients with a precision never before achieved. Nanobots, a billionth of a meter across, fixing mutations in DNA, or repairing neurons in your brain. Such are the possibilities as medicine enters the nanotechnology-era.
