Title: REDOX MEDIATOR-FUNCTIONALIZED WATER-SOLUBLE POLYMER
Abstract:
Described herein are a series of water-soluble conjugated polymers having redox mediators and functional groups on flexible side chains. The polymers may include a backbone having a conjugated polymer; a first side chain attached to the backbone, the first side chain having a ferrocene group or a derivative thereof; a second side chain attached to the backbone, the second side chain having an organic acid, a salt of an organic acid, or quaternary ammonium; and at least one of the first and second side chains having at least one of a carbon atom, a nitrogen atom, an oxygen atom, and a sulfur atom. Because of their redox activity, water solubility and ease of further coupling with versatile functional species, the polymers discussed in this application can be used as sensor interface materials for various biosensor developments.
