Figure 5. Coating and delayed release of biomolecules from MSN.

Figure 5

A–D. SEM micrographs demonstrating the coating of MSN with agarose (A,B) and gelatin (C,D) at the single particle scale (A,C) and pore scale (B,D). E. Release profiles of BSA-FITC from uncoated (black), agarose (blue), and gelatin (red) coated MSN. The coating of MSN yielded a delay in the release of BSA enabling kinetics not possible without a coating.
