In an engineering breakthrough, a Washington University in
St. Louis biomedical researcher has discovered a way to use light and color to
measure oxygen in individual red blood cells in real time.
The technology, developed by Lihong Wang, PhD, the Gene K.
Beare Distinguished Professor of Biomedical Engineering, could eventually be
used to determine how oxygen is delivered to normal and diseased tissues or how
various disease therapies impact oxygen delivery throughout the body.
The research is published March 25 in PNAS Online Early
Edition.
