The detection of biomolecules in the fields of clinical diagnosis, gene therapy and mutation analysis has become increasingly important. Therefore, it is significant for establishing a simple, rapid and sensitive detection method. Electrochemical biosensor has gained increasing interest because of its advantages such as simplicity, portability, easy to operate and low cost in the field of biomolecules detection. In order to improve the sensitivity of biosensors, different isothermal nucleic acid amplification techniques have been used in the construction of electrochemical biosensors. In this paper, we introduced the principle of electrochemical sensor briefly, summarize the main isothermal nucleic acid amplification techniques applied in electrochemical biosensors emphatically and compare the advantages and disadvantages of each technique.
