Abstract
Official abstract text for this publication.
The invention provides a quantum dot (QD) modified optical fiber-based biosensor which characterizes matrix metalloproteinase (MMP) enzyme activity at pain signaling sites in the central nervous system (CNS) in vivo. Related systems and peptide biomarker screening methods are also provided.
First claim
Opening claim text (preview).
What is claimed is: 1. A quantum dot (QD) modified optical fiber-based biosensor system adapted for evaluation of metalloproteinase (MMP) enzyme activity at pain signaling sites in the central nervous system (CNS), said biosensor system comprising: (a) a multimode silica optical fiber comprising one or more quantum dots that (1) are bioconjugated on their surface to one or more peptides having an affinity for said metalloproteinase (MMP) enzyme, and (2) that are tethered to an ins…
