The Role of Nano-Scale Colloids in Particle Aggregation and Trace Metal Scavenging

Recent observations have demonstrated that nano-scale fibrils rich   in acid polysaccharides form a major component of the population of   colloidal particles in aquatic systems. These nanoparticles form a   matrix for the formation of larger aggregates and can scavenge metal   ions from the surrounding water. A better understanding of the   structure and properties of these fibrils is crucial for   understanding their role in aquatic systems and in predicting the   properties of larger aggregates formed from them. This project is   concerned with increasing our understanding of the role that extra-  cellular polysaccharides play in the formation of aggregates and   transport of trace metals and pollutants in aquatic systems. The   project combines both experimental and modeling approaches.    (toxic metal); (toxic metals); (ions); (metal ions); (inorganics);   (inorganic compound); (inorganic compounds); (organics); (organic   compound); (organic compounds); (polysaccharides); (polysaccharide);   (chemicals of concern); (chemical of concern)
