New sensors can detect single protein molecules | QPT


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 amounts of protein, such as tracking viral infection, monitoring cells’ manufacturing
of useful proteins, or revealing food contamination.
