纳米材料指三维中的至少一维处于纳米尺度范围,或由它们作为基本单元构成的材料。目前常用于传感器件的有:金纳米粒子、半导体纳米粒子(量子点)、碳纳米材料(石墨烯、单/多壁碳纳米管、碳纳米角)等。纳米材料为稳定、特异、灵敏的生物传感器的制备提供了优秀的平台;为蛋白质、DNA等生物分子的检测提供了新策略[1]。近年来纳米材料传感器逐渐应用于小分子定性、定量检测,出现了纳米材料电
Nanomaterials refer to materials in which at least one of the three dimensions is in the nanometer scale range or consist of them as basic units. Currently used in sensing devices are: gold nanoparticles, semiconductor nanoparticles (quantum dots), carbon nano-materials (graphene, single / multi-walled carbon nanotubes, carbon nanohorn) and so on. Nanomaterials provide an excellent platform for the preparation of stable, specific and sensitive biosensors and provide new strategies for the detection of biomolecules such as proteins and DNA [1]. In recent years, nano-materials sensor gradually applied to the qualitative and quantitative detection of small molecules, there has been nano-material electricity
