Company Receives Integrated Optical Biosensor
Diagnostics Corp., based in Orangevale, Calif., has accepted delivery of a biosensor
proposed for use in diagnosing cholera, tuberculosis and malaria. The sensor could
be in clinical trials by 2012. Developed in conjunction with scientists and engineers
at Los Alamos National Laboratory in New Mexico, the device could allow relatively
untrained medical personnel to diagnose a variety of diseases rapidly. The biosensor
uses planar waveguides to bring protein-receptor pairs into proximity with one another,
thus triggering detectable fluorescence. The California company plans to commercialize
the sensor, which was created through a cooperative research and development agreement
with Los Alamos National Security LLC.
- The emission of light or other electromagnetic radiation of longer wavelengths by a substance as a result of the absorption of some other radiation of shorter wavelengths, provided the emission continues only as long as the stimulus producing it is maintained. In other words, fluorescence is the luminescence that persists for less than about 10-8 s after excitation.
