New sensors can detect single protein molecules

Modified carbon nanotubes could be used to track protein production by individual cells.

25-Jan-2017

For the first time, MIT engineers have designed sensors that can detect single protein molecules as they are secreted by cells or even a single cell. These sensors, which consist of chemically modified carbon nanotubes, could help scientists with any application that requires detecting very small ...
