Size assessing of different silica-based materials by asymmetrical flow field flow fractionation: from nanometers to micrometers

These findings demonstrate the utility of the proposed AF4-DLS analytical strategy as an effective tool for silica characterization. By enabling assessment of hydrodynamic size across nanometer to micrometer scales, this approach enhances the understanding of particle behavior, aggregation, and functionalization, thereby supporting more informed decisions in the design and applications of silica materials.
