Abstract
Ochratoxin A (OTA) is a class of mycotoxin, which are mainly produced by Aspergillus and Penicillium and widely found in in plant origin food. OTA-contaminated foods can cause serious harm to animals and humans, while high stability of OTA makes it difficult to remove in conventional food processing. Thus, sensitive and rapid detection of OTA undoubtedly plays an important role in OTA prevention and control. In this paper, the conventional and novel methods of OTA at home and abroad are summarized and compared. The latest research progress and related applications of novel OTA electrochemical biosensors are mainly described with a new perspective. We innovatively divided the recognition element into single and combined recognition element. Specifically, signal amplification technologies applied in OTA electrochemical aptasensor are proposed. Furthermore, the summary of the current limitations and future challenge in OTA analysis are discussed, which provide reference for the further researches and applications.
