| Outline of Annual Research Achievements |
Composite hydrogels of PEDOT:PSS and engineered acrylamide co-polymers are promising materials for soft bioelectronics. In this work, we set out to investigate the effect of monomer composition on the electrical conductance switching of PEDOT-based transistor devices and their potential for biosensing applications.
In FY2022, we achieved our main goal of incorporating UV-Vis-NIR spectroelectrochemistry into the study of these composite devices.
In FY2023, we achieved our goal of introducing additional functional monomers into the acrylamide co-polymer, in addition to the redox-active monomers. As a result, the oxidation potential of the dye molecule was lowered and this allowed for dye-protein binding interactions to be probed within the electrochemical stability window of PEDOT.
