Nanopowder releases power in urine (w/video)

Scientists observed an unexpected result when combining urine with a newly engineered nano-powder based on aluminum. It instantly releases hydrogen from the urine at much higher rate than with ordinary water.

New microchip technology could be used to track 'smart pills'

Researchers have developed microscale devices that relay their location in the body.

Stretching the limits of elastic conductors

High conductivity achieved by self-forming Ag nanoparticles.

Magnetic cellular 'Legos' for the regenerative medicine of the future

Researchers were able to aggregate cells that had incorporated magnetic nanoparticles using only magnets and without an external supporting matrix, with the cells then forming a tissue that can be deformed at will.

Physicists observe amplification of an optical signal within cubic nonlinear nanostructures

Scientists achieved the oherent amplification of a localized optical signal within a planar titanium nitride nanoantenna.

Dormant nanosensor awakens only in the presence of a signal of interest

Using virtually zero stand-by power, novel sensors could improve situational awareness, add smarts to Internet of Things.

Scientists find that nanoparticles from tattoos travel inside the body

The elements that make up the ink in tattoos travel inside the body in micro and nanoparticle forms and reach the lymph nodes.

Graphene-based terahertz absorbers

Researchers have shown that it is possible to create a terahertz saturable absorber using graphene produced by liquid phase exfoliation and deposited by transfer coating and ink jet printing.

Surface modification of nanomedicines enhances their therapeutic effect on brain tumors

have found a way for increasing the effectiveness of drug delivery to certain types of brain tumors, by packing epirubicin, a known antitumor agent, in specially designed polymeric micelles.
