Abstract: The present disclosure describes a new resin which can be fabricated into conductive and bioactive microstructures via two-photon polymerization. The direct incorporation of conductive poly (3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) and/or multi-walled carbon nanotubes (MWCNTs) in a poly(ethylene glycol) diacrylate (PEGDA)-based blend remarkably enhances the electrical conductivity of microstructures over 10 orders of magnitude. Including biomaterials in the resin can promote cellular adhesion and create functional biosensors made of hybrid non-conductive and conductive structures for sensitive detection. Applications include development cost effective microelectronics in a broad range of biomedical research, electronics and sensors.
