Nanogel adsorption and release on the surface. (a) Binding of ODN1-functionalized nanogels on the cODN1-functionalized surface. The first three samples are controls. Scale bar: 100 μm. (b) Kinetics of nanogel release from the hydrogel surface. Fluorescein o-methacrylate was incorporated into nanogels during polymerization for fluorescence examination. The nanogel release is indicated by the change of fluorescence intensity. Scale bar: 100 μm. (c) Electrophoretic gel images of free ODN1 incubated in the FBS solution. The degradation profile was generated from the analysis of the electrophoretic gel images.
