Analytical & Clinical Chemistry / BioTechnology

Of numerous applications in the life sciences, fluorescence detection is where our sensors excel. In fluorescence microscopy of tissues and cells and automated sequencing of DNA by labeling or tagging antibody or DNA molecules, the fluorescent label is excited by a UV source, and the identity of the base terminating the molecule is identified by the wavelength of the emitted light. Many biological molecules have an intrinsic fluorescence that can sometimes be used without the need to attach a chemical tag. These systems use high intensity light sources to excite fluorescence in the samples under observation and optically filter excitation light from emitted fluorescence which is detected by a silicon photodiode.

Other life science applications include flow cytometry, blood chemistry analysis, and food analysis. In the latter application light reflectance is spectroscopically measured from many types of chemicals such as sugar, protein, water, and fat. The same wavelengths are also utilized for high-speed grain sorting. UV excited fluorescence also provides a way to detect the presence of carcinogenic and bio-contamination.
