Novel `canary on a chip` sensor measures tiny changes in cell volume

A novel technology that can test cells in minutes for responses to any stimulus, including antibiotics, pathogens, toxins, radiation or chemotherapy, has been developed by scientists at the University at Buffalo. The paper describing the sensor will appear in the Feb. 15 issue of Analytical Chemistry, and currently is available as an "ASAP" article on the American Chemical Society Web site http://www.chemistry.org .
