1. A bio-diagnostic system comprising:
- a probe assembly configured for insertion into an animate object, the probe assembly comprising;
an optical waveguide configured for propagating a light beam;
a circular optical resonator incorporating a capture agent placed upon a binding site that is exposed to a fluid, the circular optical resonator configured to receive at least a portion of the propagated light beam and generate therefrom, a first resonant wavelength when no binding reaction is present at the binding site, and a second resonant wavelength when a binding reaction is present at the binding site, the binding reaction modifying a refractive index of the circular optical resonator;
a heating element configured for heating the binding site; and
a calorimeter for measuring a temperature of the binding site.

Abstract
An implantable diagnostic device in accordance with the present disclosure includes a probe assembly that can be implemented in a variety of ways. A few example implementations include: a needle inside which is located a bio-sensor chip (the needle being insertable into a human being); a compact package containing the bio-sensor chip (the compact package configured for placement inside a catheter); or a silicon-based bio-sensor package configured for insertion into a vein.

16. A method of using a bio-diagnostic system, comprising:
-
inserting a first probe assembly into at least one of;
a) a first conduit that is propagating a fluid containing at least one target molecule, or b) an animate object, the first probe assembly comprising a bio-sensor chip incorporating an optical waveguide and a circular optical resonator containing a capture agent placed at a binding site in the circular optical resonator;heating the binding site; deriving thermal characteristics of the at least one target molecule; propagating light through the optical waveguide; coupling at least a portion of the light from the optical waveguide into the circular optical resonator; generating in the circular optical resonator, a first resonant wavelength when no binding reaction is present at the binding site; generating in the circular optical resonator, a second resonant wavelength when a refractive index of the circular optical resonator is modified as a result of a first binding reaction at the binding site, the first binding reaction characterized by the at least one target molecule binding to the capture agent; and deriving information pertaining to the at least one target molecule upon detecting the change from the first resonant wavelength to the second resonant wavelength. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
