摘要: We implement a simple and fast technique to detect spectral shifts in the light scattering of gold nanoparticles due refractive index changes surrounding medium. Spectral are detected using spectrally balanced photon counting from spectrum colloidal nanoparticles. demonstrate use this for sensing ethanol concentration down 0.1 M.
