Abstract:

Aptamers have attracted more and more attention in clinical determination due to their specific recognition of disease biomarkers. At present,there have been many research reports,using aptamers to identify biomarkers to form determination method which has detectable signals. With the development of aptamer biosensors,its application prospects are also revealed. The combination of aptamers and functional nanomaterials can improve determination sensitivity and reduce determination limit. This review introduces the method of aptamer nanotechnology to construct electrochemical biosensors and how to improve the performance of biosensors. The application of biosensors in the determination of disease biomarkers is exemplified. The application prospects and challenges of aptamer biosensors are discussed in this review as well.

Key words: Aptamer, Biomarker, Electrochemical biosensor
