Fabrication of conductive and bioactive microdevices has garnered tremendous attention in the emerging biomedical fields, particularly organic bioelectronics and biosensing. Direct laser 3D printing based on two-photon polymerization (TPP) has shown great promise in construction of well-defined and multi-functional microdevices. Herein, we present a novel photosensitive resin for fabrication of highly conductive and bioactive microstructures via TPP. This resin is based on poly(ethylene glycol) diacrylate that is doped with poly (3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (organic semicoductor), and laminin (extracellular matrix protein) or glucose oxidase (biorecognition enzyme). We demonstrate the fabrication of hybrid microelectrodes, bioactive microstructures for cellular adhesion / spreading, and high-performance glucose biosensors. Clinical Relevance- Conductive and bioactive microelectronic devices based on the formulated resin can be utilized for neural recording / stimulation, tissue engineering, and biosensing applications.
