On behalf of the Organizing Committee, I cordially invite all the great scientists, academicians, young researchers, business delegates, and students from all over the world to attend the 19^th International Meeting on Chemical Sensors from Aug 4-8, 2023, at Changchun, China.

The International Meeting on Chemical Sensors (IMCS)–held every two years–is the world’s largest interdisciplinary forum for all aspects of chemical sensors and has developed into the most prestigious conference in this scientific area. The global conference aims to provide an international platform for scholars, scientists, engineers, and students to present and discuss the latest research, bring novel insights and inspire new ideas on functional materials and sensors technologies.

As we have seen, the omicron variant of Covid-19 is ravaging the world; to reduce the risk of epidemic spread and protect the health and vital interests of all the delegates, and provide access for those who cannot be there in person, the 19^th IMCS has to be planned in the way of combining offline and online. The topics of the conference genuinely reflect the current trends, recent advances, and new approaches in the field of Chemical and Biochemical Sensors. We are indeed in a time of great innovation in Chemical Sensors, so come and enjoy the research and report your results!

All conference sessions will be held in the “Dingxin” building of Jilin University, a national key comprehensive university under the direct administration of the Ministry of Education in China. We look forward to an extraordinary meeting with brilliant scientists from different countries worldwide and sharing epochal and exciting results in IMCS. I wish you all a fruitful conference, and I will see you soon in Changchun, China!
