| Abstract: | The TiO2 nanoparticles were prepared and modified with sodium hexametaphosphate. The interaction of TiO2 nanoparticles with human serum albumin (HSA) is studied. A new resonates light scattering (RLS) method for determination of albumin has been developed. Under the optimal conditions, linear relationships was found between the enhanced intensity of RLS and the concentration of HSA in the range from 0.2 mg/L to 65.0 mg/L. The detection limit was 0.168 mg/L. The method has been applied to the determination o... |
