(a) Degradation product, silicic acid, from silica hydrogel was monitored by measuring the absorbance of silicomolybdate complex at 400 nm (A400). The plot was fitted with a first-order degradation kinetics model. (b) Silica-coated CSP cell-seeded microgels were placed on a cell adhesive surface, and monitored their adhesion and proliferation over time. (Scale bar: 50 μm).
