| 논문초록 | Electroconductive hydrogels are promising materials for mimicking electrophysiological environments of biological system towards cardiac/neural tissue engineering, therapeutic applications, and bioelectronics. Injectable and conductive hydrogels are attractive for applications in 3D printing or for direct injection into tissues. However, current strategy of simple embedding of conductive additives (e.g., carbon materials, metal nanoparticles, and conducting polymers) has challenges to achieve stable gelation, toughness, and high conductivity. Herein, we propose two types of plant-inspired phenyl chemistry, i) rapid gallol oxidation coupled with metal reduction and ii) dynamic gallol-boronate complexation followed by exposure to biological salts for in situ fabrication of electroconductive hydrogels applicable to 3D printing and bridging of tissue defects. Our finding of phenyl chemistry would provide an insight to a variety of applications where conductive materials are needed. |
