Integrated fluorescence-based biochemical sensor
First Claim
1. A sensor assembly comprising:
- a platform having an upper surface and a bottom surface;
a light source coupled to said upper surface of said platform;
a detector coupled to said upper surface of said platform adjacent said light source; and
an encapsulating housing extending over said platform and arranged to receive light from said light source and reflect a portion of said light in a direction away from said detector;
wherein said housing has an outer surface, and a portion of said outer surface of said housing comprises a sensing surface;
and wherein the geometric configuration of said housing is such that light from said light source which is reflected off said sensing surface is diverted away from said detector.

Abstract
An integrated biochemical sensor (200) for detecting the presence of one or more specific samples (240) having a device platform (355) with a light absorbing upper surface and input/output pins (375) is disclosed. An encapsulating housing (357) provides an optical transmissive enclosure which covers the platform (355) and has a layer of fluorescence chemistry on its outer surface (360). The fluorophore is chosen for its molecular properties in the presence of the sample analyte (240). The detector (370), light sources (365, 367, 407, 409) are all coupled to the platform (355) and encapsulated within the housing (357). A filter (375) element is used to block out unwanted light and increase the detector'"'"'s (370) ability to resolve wanted emission light.
