Biogel Library-Accelerated Discovery of All-Natural Bioelectronics.

Biogels prepared from natural biopolymers are ideal candidates for constructing bioelectronics from the perspective of commercialization and environmental sustainability. However, discovering all-natural biogels that meet specific properties, such as mechanical properties, optical transparency, and stability, remains challenging. Here, our study introduces a revolutionary biogel library, a novel resource that significantly accelerates the discovery and application of suitable all-natural biogel materials for bioelectronics. Utilizing a high-throughput screening system designed with a frontend/backend development strategy, this biogel library facilitates the swift screening and customization of biogels, tailored to meet specific performance criteria. Along with demonstrating applications in soft bioelectronics and printed bioelectronics, this research also thoroughly investigates the recyclability and environmental impacts of biogels, setting a foundation for their use in sustainable, closed-loop ecological systems. This pioneering approach serves not only to foster the departure from petrochemical-derived polymers but also to bolster the advancement of environmentally responsible bioelectronics.
