Dynamic light scattering (DLS) quantitative analysis of hydrodynamic diameters and zeta-potentials of blank (i.e., non-loaded) and DOX-loaded photo-crosslinked and dual-crosslinked Alg-MA sub-microspheres. DOX encapsulation efficiencies were determined using an absorbance assay after sub-microsphere fabrication.
