Advances on the biosensor based on nanotechnology

Abstract

Biosensor is a detection instrument which is sensitive to biological substances and convert the signal of biological activity expression into electrical signal in order to determine the characteristic of samples. Besides, the development of nanoparticles greatly promoted the development and progress of biosensors. Biosensors are promising to be widely used in many fields such as food, pharmacy, chemical industry, clinical examination, biomedicine, environmental monitoring, they have gradually become a research focus on recent years hence. This paper presents a review of worldwide researches, particularly summarized and discussed in composition materials, classification, and application areas of biosensors as well. It is expected that this review can provide some help and references for further research on biosensors.
