An unprecedented high sensitive sensing of neurotransmitter dopamine at fM level was demonstrated using a poly-crystalline silicon nanowire field-effect transistor (poly-SiNW FET) fabricated by employing a simple and low-cost poly-Si sidewall spacer technique, which was compatible with current commercial semiconductor processes for large-scale standard manufacture.
利用一种采用简单且低成本的多晶硅侧壁间隔技术制造的多晶硅纳米线场效应晶体管（poly-SiNW FET），展示了在飞摩尔（fM）水平对神经递质多巴胺进行前所未有的高灵敏度传感，该技术与当前用于大规模标准制造的商业半导体工艺兼容。
