Progress in the Application of Genetic Engineering in Life Detection

Abstract

Since December 2019, the outbreak of SARS-CoV-2 has become a major public health challenge, which has a significant impact on the life, health and production of people around the world. Aflatoxin and kanamycin, which can enter the human body through food, and fluoride, which is widely present in the daily environment, are strong carcinogens. Therefore, the detection with high sensitivity, low detection limit and simple operation is needed for those pathogenic bacteria and compounds that endanger human health in life. However, the traditional laboratory operation has some defects, such as the need for expensive instruments, cumbersome operation and a certain demand for professionals. The rapid development of genetic engineering provides an excellent opportunity for the innovation of detection methods. In this paper, the contribution of genetic engineering in detection is briefly reviewed.
