Redox Mediators for Biosensor Development

Project title: Design, synthesis and characterisation of novel electrocatalytic materials and mediators for enzyme electrode based biosensor development

Researchers: Geok Hong Soon, Rodica Doaga, Susan Warren

Objective: Selected conducting and redox polymers (see below) form the basis for attachment of ferrocene derivatives enabling controlled deposition of thin films on conducting surfaces with subsequent electron transfer pathways to biocatalysts. Redox active organic dyes also form suitable films enzyme immobilisation and enhanced signalling pathways.
