The (nano)grass is greener: Porous silicon nanoneedles for your health

HOUSTON (July 30, 2010)-A newly discovered nanomaterial could improve healthcare devices by increasing energy storage, help realize implantable microchips or make better drugs, according to the cover story in July 25th Advanced Functional Materials. Scientists have created silicon nanoneedles with modulated porosity. The nanoporous needles are flexible, semiconductors, biodegradable and have a surface one hundred times larger that of solid nanowires. These unique properties of the nanowires will provide a higher energy density when used as large surface anodes in lithium batteries, constitute the active elements of bioresorbable, flexible microchips for subcutaneous implants or protect drugs while in the body and release them in a controlled manner to improve their therapeutic effect.

Treatments Here on Earth, Developed in Space

HOUSTON (April 18, 2009)-The Nanomedicine research team was the winner of The Heinlein Prize Trust Microgravity Research Competition, for a proposal entitled "Decoupling Diffusive Transport Phenomena in Microgravity." In their proposal, the team said, "Microgravity yields a valuable gift for scientists to study larger particles transported over microchannels... A particular advantage of having experimental data of free diffusion not affected by gravity at the microscale is the possibility to correlate these data with similar results obtained on Earth at the nanoscale."
