纳米材料和纳米结构表现出不同于块状材料的独特的尺寸可调和形状依赖的物理化学性质。纳米材料和纳米结构的发展为开发各种新型生物传感器打开了新的大门。本文综述了基于纳米材料和纳米结构的电化学、表面等离子体共振（SPR）、表面增强拉曼散射（SERS）和荧光生物传感器的最新进展。重点是研究如何通过使用纳米材料和纳米结构来改善生物传感器的性能，如检测极限、灵敏度和选择性。
Nanomaterials and nanostructures exhibit unique size-tunable and shape-dependent physicochemical properties that are different from those of bulk materials. Advances of nanomaterials and nanostructures open a new door to develop various novel biosensors. The present work has reviewed the recent progress in electrochemical, surface plasmon resonance (SPR), surface-enhanced Raman scattering (SERS) and fluorescent biosensors based on nanomaterials and nanostructures. An emphasis is put on the research that demonstrates how the performance of biosensors such as the limit of detection, sensitivity and selectivity is improved by the use of nanomaterials and nanostructures.
