Figure 1. Schematic illustration of the procedure for fabrication of PPF scaffolds and approaches for loading drug-coated nanoparticles.

Figure 1

Drug-coated nanoparticles were released in the medium from the scaffold. The release kinetics was studied by measuring the amount of nanoparticles in the solution using MRI contrast. The efficacy of the drug-coated nanoparticles released in the medium was measured by co-culturing the scaffolds with cells.
