▎ 摘　　要

NOVELTY - Two-photon polymerization (TPP) compatible photosensitive ink or resin comprises at least one organic semiconductor, crosslinker, photoinitiator, and solvent. USE - The resin is used in fabricated device, where the device is a micro/nanoelectronic, a battery, an optic element, a flexible electronic device, a printed circuit board, a chip-scale electronic, a chemical/biological sensor, a micro/nano electromechanical system, an organic bioelectronic, a neural interface, a neural recording and/or stimulation device, a wearable biosensor, a bioactuator, a soft robotic, a tissue engineering scaffold, or a bioprinted organ and the device is a next-generation electroactive microdevices which can be employed as chip-scale circuitry, actuators, biosensors, or neural interfaces or TPP-fabricated microdevice, for detecting an analyte in sample or subject, where the analyte is glucose, and fabrication of electrically conductive micro- and nanostructures with high spatial resolution. ADVANTAGE - The resin can be fabricated into highly conductive and bioactive three dimensional microstructures via TPP and allows the laser to penetrate deeply into the material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a fabricated device composed of the ink or resin; a method of preparing an ink or resin, comprising adding (i) the poly (3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS), (ii) the solvent, (iii) the crosslinker, and (iv) the photoinitiator, or (i) the multi-walled carbon nanotubes (MWCNTs), (ii) the solvent for MWCNTs, (iii) the PEDOT:PSS, (iv) the solvent for PEDOT:PSS, (v) the crosslinker, and (vi) the photoinitiator; and a method of detecting an analyte in sample or subject, comprising contacting the sample or subject with a device coated with a TPP compatible photosensitive ink or resin, where the ink or resin comprises at least one organic semiconductor, crosslinker, photoinitiator, and solvent and a biological molecule that binds and/or reacts with the analyte to produce a detectable event, where the device is a device, preferably (i) the ink or resin comprises two organic semiconductors, a crosslinker, a photoinitiator, and two solvents, and/or (ii) the ink or resin comprises an organic semiconductor, a crosslinker, a photoinitiator, and a solvent, and/or (iii) the biological molecule is glucose oxidase.
