Self-built protein coatings could improve biomedical devices

Fouling is a natural phenomenon that describes the tendency of proteins in water to adhere to nearby surfaces. It’s what causes unwanted deposits of protein to form during some food production or on biomedical implants, causing them to fail. Researchers at Rensselaer Polytechnic Institute are harnessing this process, which is typically considered a persistent challenge, […]

Cheap, nontoxic carbon nanodots poised to be quantum dots of the future
