Abstract: The present disclosure relates to a surface-enhanced Raman spectroscopy complex probe capable of effectively detecting a catecholamine compound even at extremely low concentrations. The complex probe includes a nanolaminate including a nanogap and metal nanoparticles. In this case, the nanolaminate and the metal nanoparticles are modified to a compound that may be bound to each functional group included in catecholamine, and thus, catecholamine included in an analyte is doubly recognized by the complex probe. In addition, since a hotspot emitting a strong SERS signal is formed by a nanogap included in a nanolaminate, it is possible to effectively detect a catecholamine compound even at extremely low concentrations.
