Dark-field spectroscopy (DFS) Dark-field spectroscopy, also known as resonant Rayleigh scattering spectroscopy (RRSS), is a technique that correlates the LSPR of single nanoparticles to enhancements in fluorescence and Raman scattering.

Nanomaterials in the form of a colloidal solution or quantum dots are attributed to have a tremendous impact in analytical chemistry for their unique physical and chemical properties (Alivisatos 2004 Katz and Willner 2004). A different methodology has been adopted to analyse vitamin Bi spectro-fluorimetrically by using cadmium selenide quantum dots (CdSe QDs), cadmium telluride (CdTe) nanorods, and silica and gold nanoparticles. A fluorescence resonance Rayleigh scattering (RRS) method was applied for determining vitamin Bi at sub-nanomolar level (Liu et al. 2006). In this technique, vitamin Bi was mixed with acidic buffer and prepared gold nanoparticles. After incubation, the solution mixture was excited in synchronous mode to obtain RRS spectra. The RRS spectral intensity correlated with the concentration of vitamin Bi.

A comparison of Eq. (12.14) with Eq. (10.43) shows that the imaginary part of a a (the matrix element for resonance Rayleigh scattering) is proportional to the matrix element for ordinary absorption. The real part of can be related to the refractive index (Box 3.3 and [14]).
