Localized surface plasmon resonance scattering imaging and spectroscopy for real-time reaction monitoring

In the last decade, plasmonic nanoparticles-based scattering imaging and spectroscopy has introduced the analysis and sensing to the single nanoparticle and molecule level, such as the biomolecules adsorption process and the quantitative detection of small molecules and ions. Recently, this technology has also been focus on the real-time and in-situ reaction monitoring, which is a new emerging branch of the single-nanoparticle imaging, revealing the reaction dynamic information and the related controlling factors. In this mini-review, recent applications of plasmon resonance scattering imaging and spectroscopy in the real-time reaction monitoring in the past 5years are highlighted and discussed.
