Research in Analyzing and Characterizing Nanoparticles in Aqueous Phase Using NMR Solvent Relaxation Method

Abstract:

Nanomaterials are playing a more and more important role in all fields, leading to increasing its release into the environment. Nanomaterials may pose a potential threat to environment and human health. Thus, there is a growing need for adaptable methods and technologies to analyze and characterize the properties of nanoparticle for purpose of understanding and minimizing the potentially unforeseen health or environmental hazards. Nuclear Magnetic Resonance (NMR) method, as a powerful analytical tool which based on the theory of solvent relaxation, breaks through some limitations of conventional methods, making it feasible in analysis and characterization of nanoparticles in aqueous phase. This paper has sketched recent research about specific surface area determination and competitive adsorption between components on the surface of nanoparticles. It also pointed out the pros and cons of NMR and conventional methods. As a result, NMR solvent relaxation will be a promising application in future.
