A multispectral microscopy imaging system is developed for the single-particle scattering spectroscopy of many individual plasmonic nanostructures simultaneously. The dispenses with need mechanical scanning sample stage and thus enables high-speed plasmon resonance nanostructure arrays. darkfield intensity images nanoplasmonic structures at wavelengths are acquired a spectral resolution 2 nm in wavelength range from 500 to 800 nm, frame rate seconds/wavelength. processed afterwards every within field view can be obtained once. more than 1000 Au colloidal nanoparticles nanofabricated nanowire array measured 5 minutes. presented promises practical application large-scale high-density sensor arrays label-free biomolecular detections near future.
