摘要

从球形红杆菌2.4.1紫色细菌中纯化的光合反应中心(pRC)沉积在从液相剥离的石墨烯载体上，并在SiO2/Si衬底表面分层，用于光电应用。光诱导的漏源电流与栅极电压的变化被证明。干燥的SiO2/Si上的光合反应中心/石墨烯复合材料表现出光化学/物理活性，这是由于石墨烯载体矩阵中的电流相互作用的结果。电流的变化对光很敏感，这是由于pRC中电荷分离的贡献，以及外加的栅极和漏源电压。

Photosynthetic reaction center/graphene bio-hybrid for low-power optoelectronics

Photosynthetic reaction center (pRC) purified from Rhodobacter sphaeroides 2.4.1 purple bacteria was deposited on a graphene carrier exfoliated from the liquid phase and layered on the surface of SiO₂/Si substrate for optoelectronic application. Light-induced changes in the drain-source current vs. gate voltage are demonstrated. Dried photosynthetic reaction centers/graphene composite on SiO₂/Si shows a photochemical/-physical activity, as a result of interaction with the current flow in the graphene carrier matrix. The current changes are sensitive to light, due to the contribution from the charge separation in the pRC, and to the applied gate and drain-source voltages.
