Advance would allow live monitoring of cell responses to chemicals

Changes induced in a single living cell by chemical signals may soon be monitored thanks to a breakthrough in measuring a single nanoparticle from a distance using light. The work by researchers from Macquarie University, the University of Adelaide and Peking University uses an optical fiber rather than a microscope. This process could help in "measuring a cell's reaction in real time to a cancer drug," allowing doctors to "tell at the time treatment is being delivered whether or not a person is responding to the therapy," said Tanya Monro, director of the University of Adelaide's Institute for Photonics and Advanced Sensing.
