Abstract: Metabolome engineering, including profiling and manipulation of small metabolites, is essential in monitoring and control the physiological and pathological process in bio-systems. Metabolic detection is the key in metabolome engineering. Despite that mass spectrometry (MS) enjoys huge application benefits over traditional methods in metabolic detection, present MS approaches, particularly laser desorption/ionization (LDI) MS techniques, urgently need designed materials as efficient matrices and their LDI mechanism is still to be explored, in order to overcome the major limitations in terms of sensitivity, selectivity, throughput, accuracy, and practicability for metabolome engineering. In this talk, we show our recent progress on the design of inorganic particles as novel matrices for LDI MS analysis and their practical application in detection of small metabolites in bio-fluids, for advanced metabolome engineering toward large-scale biomedical use.
