August 10, 2009 — A new material developed at the University of Virginia – an oxygen nanosensor that couples a light-emitting dye with a biopolymer – simplifies the imaging of oxygen-deficient regions of tumors.

Oxygen nanosensors are powerful new research tools that one day may also be used for the diagnosis and detection of diseases and for planning treatment strategies.
