iPhone plus nanoscale porous silicon equals cheap, simple home diagnostics

Tue, 06/11/2019 - 21:59
The simplest home medical tests might look like a deck of various silicon chips coated in special film, one that could detect drugs in the blood, another for proteins in the urine indicating infection, another for bacteria in water and the like. Add the bodily fluid you want to test, take a picture with your smart phone, and a special app lets you know if there is a problem or not.

Plot twist: Straightening single-molecule conductors improves their performance

Tue, 06/11/2019 - 17:36
Researchers have created single-molecule nanowires, complete with an insulation layer, up to 10 nanometers in length. When they measured the electrical properties of these nanowires, the researchers found that forcing the ribbon-like chains to be flat significantly improved their conductivity compared with a twisted conformation.
