Detection of biological molecules using boronate-based chemical amplification and optical sensors
First Claim
1. An implantable amplification system comprising a polymer matrix and an amplification component contained in said matrix, said amplication component producing a polyhydroxylated analyte signal upon interrogation by an optical system, wherein said amplification component requires intramolecular electron transfer for production of said signal and comprise a compound of the formula ##STR2## wherein:
- D1 is a dye selected from the group consisting of fluorescent dyes, luminescent dyes and colorimetric dyes;
R1, R3 and R4 are each independently substituents which alter the electronic properties of the groups to which they are attached or are functional groups which can form covalent linkages to the surrounding polymer matrix;
each R2 is a member independently selected from the group consisting of hydrogen and C1 -C4 alkyl;
each L1 and L2 is a linking group having from zero to four contiguous atoms selected from the group consisting of carbon, oxygen, nitrogen, sulfur and phosphorus;
Z is a heteroatom selected from the group consisting of nitrogen, sulfur, oxygen and phosphorus; and
x is an integer from zero to four.

Abstract
Methods are provided for the determination of the concentration of biological levels of polyhydroxylated compounds, particularly glucose. The methods utilize an amplification system that is an analyte transducer immobilized in a polymeric matrix, where the system is implantable and biocompatible. Upon interrogation by an optical system, the amplification system produces a signal capable of detection external to the skin of the patient. Quantitation of the analyte of interest is achieved by measurement of the emitted signal.
