Biosensor Listens to Cellular Monologues in Real Time

Cells are the ultimate ensemble cast members, but they can also deliver soliloquies—if the cells ever get the chance to have the stage to themselves. To give individual cells their turn in the spotlight, an international team of scientists has built a sort of microfluidic theatre, complete with a gold-coated glass stage and a nanoplasmonic lighting system.With the right stage management, individual cells can be induced to reveal their innermost motivations, the signals they would transmit
