What could tiny, smaller-than-dust particles do? How could they ever be useful? Researchers have found potential use for the tiny, smaller-than-dust particles called the Quantum dots. A recent study by Professor Lin at the University of Washington shows that the light-activated quantum dots can be used to "trigger" neurons. Such "triggering" of neural cells is quintessential for nerve signalling, something which is degenerated in people with conditions like the Alzheimers, epilepsy etc. The study has been reported in the latest issue of Biomedical Optics Express and is available here.
