Direct radiolabeling of nanographene materials enhances bioimaging accuracy, reduces biases

Positron emission tomography plays a pivotal role for monitoring the distribution and accumulation of radiolabeled nanomaterials in living subjects. The radioactive metals are usually connected to the nanomaterial through an anchor, a so-called chelator, but this chemical binding can be omitted if nanographene is used, as American scientists report in the journal Angewandte Chemie

Researchers succeed in activating a 'single-molecule switch'

Everybody knows the force that is required to activate a light switch on a wall - a finger is enough. But how much force do you need to apply if the device was dramatically reduced to the "nanoscale world", that is, how much force do you need to operate a "single-molecule switch"? This fundamental question is related not only to basic science but also to potential future applications of molecular devices.
