Aptamers and Their Application in Food Safety

Aptamers,as new biological recognition element with potential substitute for antibody,are research focus recently. Aptamers have been isolated against different molecule classes including antibiotic,heavy metal ions,foodborne pathogens,biotoxin and others in food safety,and various aptamer- based detection assays have been developed for them. Characteristic,superiority,identification mechanism,and selection in vitro of aptamers were introduced. Recsent developments of application about aptamers in food safety were reviewed.
