Plasmonic single nanoparticle for resonance light scattering imaging analysis and applications

Metallic nanoparticles are used in every stage of science and are still charming the researchers to explore the localized surface plasmon resonance (LSPR) properties for the promising application of sensors and catalysts. In this review, recent progresses on silver-based and gold-based single nanoparticle for reso-nance light scattering imaging analysis and applications are presented. Firstly, fundamental principles and technique of dark -field microscope (DFM) coupled the LSPR spectroscopy are described. Then, the species of silver-based and gold-based single nanoparticle are outlined, with an emphasis on the reso-nance light scattering imaging analysis of silver-based and gold-based single nanoparticle. Finally, recent achievements of the plasmonic single-particle imaging analysis technique in analytical determinations and reaction monitoring are also comprehensively introduced. We hope to shed some light on the forthcoming study by showing these advances and some future challenges of resonance light scattering imaging analysis.(c) 2023 Elsevier B.V. All rights reserved.
