Food borne diseases caused by mycotoxins, food borne bacteria and other hazards cause 550million infections and hundreds of thousands of deaths worldwide every year, causing huge economic losses and social burden. The establishment of highly sensitive on-site detection technology is of great significance for early, immediate and effective supervision of food safety and protection of consumer health. Recently, Associate Professor Wang Chongwen of the school of life sciences of Anhui Agricultural University developed a highly sensitive immunochromatographic detection technology based on membrane SERS tags, which can quickly and accurately identify a variety of mycotoxins and pathogenic bacteria in complex food samples and environmental samples. The sensitivity of detecting toxins is up to 1 pg/ml, the sensitivity of detecting bacteria is up to 10 cells/ml, and the detection time is less than 20 minutes. Relevant research contents were published in the famous journals in the field chemical engineering journal and biosensors and bioelectronics. Associate Professor Wang Chongwen is the first and corresponding author of this technology, and researcher Wang Shengqi of Military Medical Research Institute and Professor Gu Bing of Guangdong Provincial People’s hospital are the co corresponding authors.
In addition, Associate Professor Wang Chongwen recently developed a mycotoxin immunochromatographic detection kit based on magnetic enrichment/fluorescence enhancement mechanism, which can detect three common mycotoxins (aflatoxin B1, fumonisin B1 and ochratoxin A) in food crops (such as corn, grain, etc.) with high sensitivity at the same time. The reagent is easy to operate. High sensitivity analysis can be achieved by using UV flashlight or portable fluorescence reader. The detection time is less than 35 minutes, and the sensitivity is 1-20 pg/ml. Relevant papers were published in the first district Journal of the Chinese Academy of Sciences,”sensors and actuators b:chemical”, with Dr. Zheng Shuai as the first author, Associate Professor Wang Chongwen, Professor Jin Qing and researcher Wang Shengqi of the Academy of military medicine as co correspondents, and our university as the first unit.
Since Associate Professor Wang Chongwen introduced talents to our university in 2018, with the strong support of the University and the College of life sciences, he has made in-depth cooperation with the military Key Laboratory of new technologies for molecular diagnosis of infectious diseases of the Academy of military medicine, achieved a series of scientific research achievements, and developed a variety of highly sensitive on-site detection technologies and products.
