Electrically conductive hydrogels are soft, polymeric networks that combine hydrogels’ unique properties, such as biocompatibility, high level of hydration, and high diffusivity of small molecules, with electroactive polymers’ redox switching, optical switching, and electrical conductivity. They have been used in implantable biosensors, biorecognition membranes, electrostimulated or programmed drug delivery systems, and low interfacial impedance layers on neuronal prostheses. Utilizing carbon nanotubes and conducting polymers as the electroactive component, we have synthesized electroconductive hydrogels via oxidative cross-linking or click chemistry. The electroconductivity, cross-linking density, and other physic-chemical properties of the synthesized hydrogels can be easily controlled. We show that electroconductive hydrogels can be utilized in electro-stimulated drug delivery and stem cell differentiation. |
