文摘
- •
A Fourier transform imaging spectrometer for measuring the scattering spectra of single metallic nanoparticles is presented.
- •
The current imaging spectrometer setup routinely allows collecting signals from more than 50 individual nanoparticles in parallel.
- •
The signal response of single metallic nanoparticles due to changes of their local environment was investigated.
- •
The spatial distribution of BSA adsorption on single nanoparticles is monitored.
- •
The presented Fourier based imaging spectrometer allows the fast and cost-efficient readout of scattering spectra of single nanoparticles.
