Abstract: Provided is a dielectrophoresis-based dynamic Surface-Enhanced Raman Spectroscopy (SERS) nanoelement for the classification and analysis of metabolites. A method for analyzing metabolites using a dielectrophoresis-based dynamic SERS nanoelement according to an embodiment of the present invention may comprise the steps of: preparing a dynamic SERS nanoelement in which a surface region is formed as an array; applying voltage to the dynamic SERS nanoelement; and classifying the metabolites of an analysis subject according to region by controlling the polarity of the dynamic SERS nanoelement according to the voltage applied.
