Biologically inspired peptide- and protein-based materials are at the forefront of organic bioelectronics research due to their inherent conduction properties and excellent biocompatibility. Peptides have the advantages of structural simplicity and ease of synthesis providing credible prospects for mass production, whereas naturally expressed proteins offer inspiration with many examples of high performance evolutionary optimised bioelectronics properties. We review recent advances in the fundamental conduction mechanisms, experimental techniques and exemplar applications for the bioelectronics of self-assembling peptides and proteins. Diverse charge transfer processes, such as tunnelling, hopping and coupled transfer, are found in naturally occurring biological systems with peptides and proteins as the predominant building blocks to enable conduction in biology. Both theory and experiments allow detailed investigation of bioelectronic properties in order to design functionalized peptide- and protein-based biomaterials, e.g. to create biocompatible aqueous electrodes. We also highlight the design of bioelectronics devices based on peptides/proteins including field-effect transistors, piezoelectric energy harvesters and optoelectronics.

基于肽和蛋白质的生物材料的电子学

受生物启发的基于肽和蛋白质的材料由于其固有的传导特性和出色的生物相容性而处于有机生物电子学研究的前沿。肽具有结构简单和易于合成的优点,为大规模生产提供了可靠的前景,而自然表达的蛋白质则为高性能进化优化生物电子学特性的许多例子提供了灵感。我们回顾了自组装肽和蛋白质的生物电子学的基本传导机制、实验技术和示例应用方面的最新进展。多种电荷转移过程,如隧道、跳跃和耦合转移,存在于以肽和蛋白质为主要构件的天然生物系统中,可以在生物学中进行传导。理论和实验都允许对生物电子特性进行详细研究,以设计功能化的基于肽和蛋白质的生物材料,例如创建生物相容性水性电极。我们还重点介绍了基于肽/蛋白质的生物电子设备的设计,包括场效应晶体管、压电能量收集器和光电子学.
