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.
