Optical Detection Technologies are used in probably 85% of clinical chemistry and immunoassay analyzers. These techniques provide highly sensitive and accurate ways to analyze and detect minute concentrations of hormones, cancer markers, drugs, infectious disease organisms, and contaminants. Biological constituents such as glucose, cholesterol, and other metabolites are routinely measured in this way.
Optical screening detectors use specific wavelength light sources to excite and identify labeled targets. More recently, multi wavelengths are being used to broaden the information gathered in fluorescence-based assays. Some detection methods used for analysis are time-resolved fluorescence for continuous-flow microfluidic systems, and high-throughput imaging for DNA testing.
We have developed a number of products that use Optical Detection Technology, including a photon-counting immunoassay device, fluorescence-based dissolved oxygen probes, and a device that uses reflectance photometry. The analysis method is well-suited for lab-on-a-chip applications and microfluidic devices that use small or low volume sample sizes, micro-arrays and other miniaturized high-throughput devices.
