Gold-plated nano-bits find, destroy cancer cells

Comparable to nanoscale Navy Seals, Cornell scientists have merged tiny gold and iron oxide particles to work as a team, then added antibody guides to steer the team through the bloodstream toward colorectal cancer cells. And in a nanosecond, the alloyed allies then kill the bad guys - cancer cells - with absorbed infrared heat.

Triboelectric nanogenerator extracts energy from ocean waves

Researchers are aiming to use ocean waves to produce energy by making use of contact electrification between a patterned plastic nanoarray and water. They have introduced an inexpensive and simple prototype of a triboelectric nanogenerator that could be used to produce energy and as a chemical or temperature sensor.
