Journal of Nanomaterials,Special Issue on Nanosensors:From Fundamentals to Applications基于纳米材料和纳米科技的蓬勃发展,新一代的传感技术越来越向原子及分子尺度发展。纳米传感器具备超高的探测灵敏度,优异的光谱选择性,低功率损耗,多样性及灵活性等优点。例如,利用纳米碳管制备出的超高分辨率质量传感器(1.7 yg,1yg=10-24 g),其性能指标比传统的传感器高3到4个量级。另一方面,利用纳米结构制备的纳米光电传感器的光谱响应要大大高于传统半导体薄膜材料制备的类似器件。可以预见,纳米科学和纳米技术将引领未来高性能传感器的研究方向。
Journal of Nanomaterials, Special Issue on Nanosensors: From Fundamentals to Applications Based on the rapid development of nanomaterials and nanotechnology, a new generation of sensing technologies is increasingly being developed at atomic and molecular scales. Nanosensors have superior detection sensitivity, excellent spectral selectivity, low power loss, versatility and flexibility. For example, ultra-high resolution mass sensors (1.7 yg, 1yg = 10-24 g) made with carbon nanotubes have performance specifications that are three to four orders of magnitude higher than traditional sensors. On the other hand, nanostructured nanostructured photoelectric sensors have significantly higher spectral response than similar devices made from conventional semiconductor thin film materials. It is foreseeable that nanoscience and nanotechnology will lead the way in the future of high-performance sensors.
