Semi-degradable Multifunctional Hydrogel Constructs for the Repair of Cartilage Defects

摘要

SEM analysis showed that the particles were spherical in shape with a smooth surface, with an average diameter of 29.98 ± 17 μm. Figure 1 shows the microparticles embedded within the hydrogelmatrix using the Suspension method (a) and the Direct Incorporation Method (b). The large pores seen in hydrogels made using the Direct Incorporation method are attributed to the evaporating solvent during hydrogel formation.
