Luminescent in vivo glucose measurement
First Claim
1. A luminescent in vivo glucose measurement method for measuring a glucose level in an interstitial fluid of a subject, comprising the steps of:
- displacing luminescent molecules and associated captive glucose analogue molecules into an illumination region;
illuminating said displaced luminescent molecules within said illumination region with illuminating light, said displaced luminescent molecules and associated captive glucose analogue molecules being contained within an implanted luminescent in vivo measurement apparatus implanted within said interstitial fluid of said subject; and
measuring an emitted light, said emitted light being emitted in response to said illumination;
wherein said emitted light is related to said glucose level in said interstitial fluid.

Abstract
A luminescent in vivo glucose measurement method and apparatus is provided. The luminescent in vivo glucose measurement method includes the steps of illuminating displaced luminescent molecules with illuminating light, the displaced luminescent molecules and associated captive glucose analogue molecules being contained within an implanted luminescent in vivo measurement apparatus implanted within the interstitial fluid of the subject, and measuring an emitted light, the emitted light being emitted in response to the illumination, wherein the emitted light is related to the glucose level in the interstitial fluid.

13. A luminescent in vivo glucose measurement method for measuring a glucose level in an interstitial fluid of a subject, comprising the steps of:
-
(a) providing an implanted luminescent in vivo measurement apparatus within said interstitial fluid, said implanted luminescent in vivo measurement apparatus comprising a container having an interior region, an illumination region wherein light may enter said interior region, an agglutinating layer on at least one surface of said interior region and apart from said illumination region, and luminescent molecules and associated captive glucose analogue molecules reversibly attached to said agglutinating layer;
(b) providing a means of allowing glucose from the subject to enter said interior region, said glucose causing said luminescent molecules and associated captive glucose analogue to become displaced from said agglutinating layer and into said illumination region;
(c) illuminating displaced luminescent molecules within said illumination region; and
(d) measuring an emitted light from said displaced luminescent molecules, said emitted light being emitted in response to said illumination;
wherein said emitted light is related to said glucose level in said interstitial fluid. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
