Abstract
Fluorescence photobleaching recovery, long a staple tool of complex fluid e xperimentation, is discussed as a method for size characterization of collo idal particles. Specific comparisons are made to dynamic light scattering, which is often used for sizing particles despite some important limitations . The capabilities of fluorescence photobleaching recovery for size determi nation are demonstrated for aggregating core-shell silica-polypeptide compo site particles suspended in polar organic solvents.
