CRISPR-Based Biosensor in Foodborne Pathogen Detection

In the whole food supply chain, sensors can be used in many critical control points, ranging from breeding environment, processing equipment, product packaging, distribution vehicles, to monitor the pH, temperature, hazardous gases, pathogens, toxins, viruses, etc. Novel molecular biological techniques, such as CRISPR showed great potential in biosensing due to its precise nucleic acid-targeting and cutting ability. When integrate with all kinds of biosensors, CRISPR-based sensor is able to detect nucleic acid targets (pathogens and viruses) and non-nucleic acid targets (antibiotics, toxins, iron) in the food supply chain with ultra-high sensitivity. His goal is to develop low-cost, user-friendly, rapid and sensitive detection methods/ instruments with automatic control and detection system for the in-field, real-time monitoring of environmental and food hazards. Taking advantage of CRISPR technology, mechanical engineering and artificial intelligence, lots of the targets will be detected in a very short detection time.


Fei Jia is currently a Research Scientist in the Department of Biological and Agricultural Engineering at the University of Arkansas. He finished 2 years of training experience as a Postdoctoral research associate in Agricultural Engineering at Zhejiang University. He received his Ph.D. degree at China Agricultural University with a Food Science major, and a Master’s degree at Jiangnan University with an emphasis in Food Science and Technology. He also spends 18 months at the department of Food Science, Purdue University. His research is to develop CRISPR based-biosensor (electrochemical, low field NMR, QCM and optical) for the rapid detection of pathogens and antibiotics in the food (poultry and pork) supply chain. He served as Chair of the American Society of Agricultural and Biological Engineers (ASABE) ITSC-230 Technical Committee on Biosensors. He published over 30 journal articles and gave 7 invited talks at international meetings.
