Abstract: Biosafety has seriously threatened the survival and development of human beings. Under the situation of the coronavirus disease 2019 (COVID-19) epidemic and the normalization of anti-epidemic, biosafety prevention and control is becoming more and more important, which is directly related to the development of society, economy and politics. At the beginning of COVID-19 epidemic, there was a serious lack of personal protective equipment, due to the shortage of medical emergency supplies and the lack of ability to public health emergencies. In the face of the severe challenge of the epidemic, interdisciplinary and multidisciplinary cooperation is the key to scientific epidemic prevention. The characteristics of the material, such as optical, electrical, acoustic, magnetic, thermal, are helpful for the design and preparation of multi-functional new materials, which can meet the requirements of biosafety prevention in detection, prevention and treatment. We should give full play to the advantages of biosafety and materials science. Using new biosafety materials to overcome the shortcomings of traditional materials can improve or provide new detection methods. Not only can we use biosafety materials to develop a variety of highly effective, low toxicity drugs and vaccines, but also to produce multifunctional masks and protective clothing. What we have done has contributed to the preparation of medical emergency supplies and to the fight against the COVID-19 pandemic. At the same time, the toxicity of new biosafety materials can not be ignored. Only by accelerating industrialization based on basic research and practical problems can we better cope with other emerging outbreaks of infectious diseases in the future.
