Biosensor Based on Graphene Directly Grown by MW-PECVD for Detection of COVID-19 Spike (S) Protein and Its Entry Receptor ACE2.

报道了基于石墨烯场效应晶体管（G-FET）检测SARS-CoV-2刺突蛋白S及其受体ACE2的生物传感器。石墨烯通过微波等离子体增强化学气相沉积（MW-PECVD）直接在SiO2/Si基底上生长，并与铜箔CVD生长后湿法转移到玻璃的商用石墨烯器件进行对比。利用拉曼散射光谱和原子力显微镜表征石墨烯结构与表面形貌。石墨烯表面用1-吡喃丁...
