Stepwise encapsulation of magnetic nanoparticles into amphiphilic block copolymer vesicles through controlled water dialysis
Block copolymer self-assembly is a non-equilibrium process in most experimental conditions used today. In contrast, the controlled water dialysis of block copolymer solution in non-selective solvent against water affords copolymer structures at thermodynamic equilibrium. We propose to investigate the stepwise encapsulation of hydrophobic coated magnetic nanoparticles into block copolymer vesicles/micelles with the help of a controlled water dialysis pathway recently developed by the D22 team. It is hypothesized that nanoparticles can influence the pathway to the formation of polymer vesicles. The proposal aims at providing new insights into the formulation of various copolymer self-assemblies used as contrast agents for MRI applications.
