Thermal gradients are shown to enhance spin transport in graphene

NanoWerk.com - Tue, 12/05/2017 - 16:29
Researchers have demonstrated that the application of a thermal gradient in spintronic devices can cause spin signal to increase as a result of a novel thermoelectric phenomenon predicted and subsequently observed in graphene. Specifically, the enhanced spin signal is two orders of magnitude larger than anything previously reported for thermal effects in metals.

Programmable drug delivery platform combats diseased cells at genetic level

ScienceDaily.com: Nanotechnology News - Mon, 12/04/2017 - 19:53
A research team has developed a unique linker technology to connect a synthetic drug delivery vehicle referred to as a nucleic acid nanocapsule (NAN) with a new peptide cross-linker approach. The NAN enables both a small molecule drug and a nucleic acid -- RNA or DNA -- to be delivered to a cell. This combination generates a nanocapsule capable of shepherding genetic or pharmaceutical molecules to a target on or within a cell.
