Micro/Nano Biosensing System and Its Application on Biomedicine

摘要

Development of microano biosensors had not only established a fresh platform but also expanded the essential scopes for the biomedical researches which covers science, engineering, medicine and agriculture fields. By these advanced sensing technologies, people can observe the molecules transportation in the cell and the micro interaction between cells, then the prior hypothesizes and theories can be validated with the success of these technologies; on the other hand, these technologies gradually play an important role for the biomedical detection. The biosensor showed a diverse developments and applications with respect to the impact of nano technology. In this article, we briefly described the sensing principle and also some advance and unique characteristics of microano biosensor. The advanced biosensing systems which were developed for the detection of biochemistry, immunological proteins and genomic nucleotides in human blood were taken as examples to compare the developing technologies with current methods; we addressed some possible challenges for the new ones. Finally, we summarized the chances that microano biosensors can play in the molecular diagnosis of human blood, and proposed the future trends and challenges for the new sensing technologies based on the market and practical considerations.
