Nanoparticle molecular probes drastically reduce cost of powerful microscopy technique

A dye-based imaging technique known as two-photon microscopy can produce pictures of active neural structures in much finer detail than functional magnetic resonance imaging, or fMRI, but it requires powerful and expensive lasers. Now, a research team at the University of Pennsylvania has developed a new kind of dye that could reduce the cost of the technique by several orders of magnitude.

New, all-graphene photodetector is both flexible and transparent

Researchers at the University of Exeter have developed a new photoelectric device that is both flexible and transparent. The device converts light into electrical signals by exploiting the unique properties of the recently discovered materials graphene and graphExeter. GraphExeter is the best known room temperature transparent conductor and graphene is the thinnest conductive material.
