As the youngest competence cluster of the DBE, it was established due to the rapid development of technologies and approaches in fields such as the analysis and diagnosis of metabolic activities, forensic evidence research, and human breath-related research. This cluster actively conducts cross-entity collaboration. It not only maintains close connections with industrial partners, law enforcement agencies, and medical institutions but also carries out in-depth cooperation with the research teams of the "Competence Cluster for Data Driven Modelling & Analysis", jointly promoting technological innovation and practical application in relevant fields.
