Effect of Surface–Molecule Interactions on Molecular Loading Capacity of Nanoporous Gold Thin Films

Surface–molecule interactions play an essential role in loading capacity and release kinetics in nanostructured materials with high surface area-to-volume ratio. Engineering the surfaces via immobilizing functional moieties is, therefore, a versatile means to enhance the performance of drug delivery platforms with nanostructured components. Nanoporous gold (np-Au), with its high effective surface area, well-established gold-thiol chemistry, and...
