1. An electro-optical sensing device for detecting the presence or concentration of an analyte, comprising:
- a housing having an outer surface;
a plurality of indicator molecules located on at least a portion of the outer surface of the housing;
a circuit board housed within the housing;
a support member having a side that lies on a plane that is substantially perpendicular to a plane on which a top side of the circuit board lies;
a radiation source attached to said side of the support member and positioned a distance above the top side of the circuit board; and
a photodetector connected to the circuit board for detecting a response of the indicator molecules.

Abstract
The present invention provides an electro-optical sensing device for detecting the presence or concentration of an analyte. More particularly, the invention relates to (but is not in all cases necessarily limited to) optical-based sensing devices which are characterized by being totally self-contained, with a smooth and rounded oblong, oval, or elliptical shape (e.g., a bean- or pharmaceutical capsule-shape) and a size which permits the device to be implanted in humans for in-situ detection of various analytes.
