Rayleigh scattering technique
WebA simple and sensitive Rayleigh light scattering (RLS) method is developed for the quantification of p-cresol in exhaled breath condensate (EBC). The method is based on an aggregation of anthracene nanoparticles in acidic media after adding the p-cresol which results in a marked enhancement in RLS intensity at 410 nm. WebRayleigh scattering. Rayleigh scattering is a type of scattering that occurs when electromagnetic waves, such as light, encounter particles or obstacles much smaller than …
