Recently, the Ministry of Education issued the certificates for Outstanding Achievement Award for Scientific Research in Higher Institutions (Science and Technology) in 2022, and Prof. Fang Yu’s research achievement of "Key Technologies and Portable Detection Equipment for Explosive/Illicit Drug Film Fluorescence Sensors" won the first prize of the 2022 Technological Invention Award, and it is the first time that Shaanxi Normal University has won this honor.

  The achievement was jointly submitted by Shaanxi Normal University and Shenzhen SRED Security and Surveillance Technology Co., Ltd., with SNNU as the first responsible institution, and the main participants are Prof. Fang Yu, Prof. He Gang, Prof. Xin Yunhong, Assoc. Prof. Liu Taihong, Prof. Peng Haonan and Engineer Xu Liang.

  Film fluorescence sensing is a new generation of ultra-sensitive detection technology of micro-trace substances recognized internationally. It has unique advantages and great application potential in the field of rapid, sensitive and portable network detection of dangerous, toxic and harmful chemicals that are related to public safety and national security capacity building.

  In view of the obstacles such as the difficulty in achieving high performance of sensitive materials, the monopoly of sensor structure by foreign companies' patented technology, the high threshold in equipment development, and the high technological difficulties, the team carried out the whole chain research of "sensitive film ←→ sensor ←→ detection equipment" around the core technology of film fluorescence sensing, and have achieved a major breakthrough in the development of explosive/illicit drug detection technology and equipment through more than 20 years of efforts, developing a film fluorescence sensing technology system with complete independent intellectual property rights. After rigorous review and selection by the International Union of Pure and Applied Chemistry (IUPAC), film fluorescence sensors were selected as one of the top ten emerging technologies in chemistry in 2022.

  Shenzhen Security and Surveillance Technology Co., Ltd., founded in 2014 on the basis of this technology system, has grown into a chemical sensor company with major influence in the industry, and its products have played an important role in the security of major events and important places such as the 19th CPC National Congress, the G20 Summit, the Commander’s Train, and the Ugandan Presidential Palace, and have been deployed as a military gear since 2019.

  The Outstanding Achievement Award for Scientific Research in Higher Institutions (Science and Technology) is an award established by the Ministry of Education to encourage teachers, scientific and technological workers and research organizations in higher institutions who have made outstanding contributions to the promotion of scientific and technological progress. It is an important science and technology award with fierce competition second only to the National Prize for Natural Sciences, the National Award for Technological Invention and the National Prize for Progress in Science and Technology, which evaluation is open to all higher education institutions in China, and reviewed and selected by peer experts across the country.
