Study probes how nanoparticles bind to blood proteins at interfaces

New research indicates that nanoparticles are able to change their binding at surfaces to proteins abundant in the blood depending on whether the protein is bound to fat molecules at the time. The findings indicate how nanoparticles interact with blood proteins in the body by influencing the efficiency of the nanoparticle transport to surfaces.
