在场效应晶体管(FET)上的卟啉附着金纳米颗粒(AuNPs)中设计了一种生物激发的光响应。该系统模拟光合作用的电子传递，使用卟啉衍生物作为光敏剂，使用AuNPs作为光电子计数装置。通过形成自组装单分子膜，将卟啉保护的AuNPs固定在FET栅极上。在有机电解液存在的情况下，通过改变场效应管上的栅极电压，光诱导的电子转移导致金纳米粒子的单电子转移。将其他功能分子进一步连接到这个系统上，应该能够实现各种其他潜在的功能。本文是题为：光合作用研究的可持续性：生产清洁能源的关键“特刊的一部分。
A bio-inspired photoresponse was engineered in porphyrin-attached Au nanoparticles (AuNPs) on a field-effect transistor (FET). The system mimics photosynthetic electron transfer, using porphyrin derivatives as photosensitizers and AuNPs as photoelectron counting devices. Porphyrin-protected AuNPs were immobilized onto the gate of an FET via the formation of self-assembled monolayers. Photoinduced electron transfer from the porphyrin led to single electron transfer at the Au nanoparticles, which was monitored via a changing gate voltage on the FET in the presence of organic electrolyte. The further attachment of other functional molecules to this system should enable various other potential functionalities.
