Researchers develop GO-based injectable bioelectrodes with tunable degradability
Researchers from Gwangju Institute of Science and Technology (GIST) and Chonnam National University Medical School have developed graphene-based conductive hydrogel electrodes that offer convenience of use, controllable degradation, and excellent signal transmission.
Implantable bioelectrodes are electronic devices that can monitor or stimulate biological activity by transmitting signals to and from living biological systems. Such devices can be fabricated using various materials and techniques. But, because of their intimate contact and interactions with living tissues, selection of the right material for performance and biocompatibility is crucial. Conductible hydrogels are attracting great attention as bioelectrode materials owing to their flexibility, compatibility, and excellent interaction ability. However, the absence of injectability and degradability in conventional conductive hydrogels limits their convenience of use and performance in biological systems. The researchers' new graphene-based conductive hydrogels possess injectability and tunable degradability, furthering the design and development of advanced bioelectrodes.
