浓度测定

Based on a lot of documents, this thesis chooses several kinds of organic or drug small molecular, using resonance light-scattering technique, UV/Vis absorption spectra method, fluorescence spectra method and 1H NMR spectra method studied the interaction mechanisms of those small molecular and biopolymer. Base on the variation of the intensity of resonance light scattering is ratio to the concentration of the protein and DNA establishes several new determination methods of protein and DNA.
