“Life Analysis” is a newly emerging branch of analytical chemistry, which was proposed by an innovative research group at Nanjing University in 2003. It has been taking shape since the late 1990s through the integration of analytical chemistry with life sciences, clinical medicine, physics, and materials science. This emerging interdisciplinary field aims to investigate various components and structural units of substances in life systems, as well as their dynamic changes during interaction processes. It seeks to establish new principles, methods, and techniques for the detection and tracing of biomolecules in biological processes, enabling the rapid, highly sensitive, highly specific, and highly accurate qualitative and quantitative monitoring of biological substances. Furthermore, it facilitates molecular recognition and the extraction of biological information.
