High sensitivity optical detection system
A high sensitivity optical system for detection of chemical and biological analytes is disclosed comprising a vessel containing the chemical and biological analytes, a light-guide inside the vessel but separated from the vessel by the chemical and biological analytes, one or more excitation light sources at one end of the vessel, a detector at another end of the vessel, one or more excitation filters between the excitation light sources and the vessel, one or more emission filters between the vessel and the detector, and light directing components. The novel optical system is secured in a housing and connected to devices extrinsically or intrinsically for data input, process, display, storage, and communication. This optical system could enable clinical level diagnosis of a wide range of diseases in an inexpensive mobile point-of-care format. Furthermore, the form factor of the optical system can be significantly reduced to form a highly integrated lab-on-a-chip system.
