| Abstract |
Localized surface plasmon resonance (LSPR), which occurs in roughened metal nanoparticles (NPs), has been the most important source of SERS enhancement, and various types of metal nanoparticles have been developed so far. Among the metal nanoparticles, AgNP generates a strong electromagnetic field and is most widely used in SERS study. In addition to electromagnetic field effect, an additional source of SERS enhancement is the chemical enhancement effect, in which the polarizability is increased by charge transfer from the atomic band of the nanoparticle used as the substrate to the analyte. Noble metal/semiconductor nanocomposites can expect both electromagnetic field and chemical enhancement effects. In this study, we synthesized Ag@Cu2O core-shell nanoparticle and investigated its properties and possible of application for the detection of effective biomaterials. |
