Biological signals transmitted by living matter can be transduced into electronic pulses using organic bioelectronics. Seamlessly connecting living tissue with conducting materials in this way poses great implications for the future of biosensing and tissue engineering. Conjugated polymers (CPs) present an advantageous platform for developing these technologies as they demonstrate good biocompatibility, can be engineered into various form factors and can be tailored to a specific function through chemical design. Progress in developing solid-state devices based on CPs such as field-effect transistors (OFETs) and photovoltaics (OPVs) has culminated in a rich understanding of their structureproperty relationships. Consequently, their mechanical and electronic properties can be optimised through judicial chemical design and post processing techniques. However, for in vivo or in vitro implementation, the material requirements must be further extended to consider the biological properties. In particular, the ability of the material to support and facilitate cell growth is paramount to enabling these technologies.
