(a) Schematic representation of AuNP containing monolayer entrapped drugs and their delivery into cell through monolayer membrane interaction. (b) Structure of NPs and entrapped guest molecules: Bodipy as a fluorescent probe, and TAF (tamoxifen) and LAP (β-lapachone) as drugs. The number of encapsulated guests per particle is given under the structures. Cytotoxicity of the NPs was measured by alamar blue assay after 24 h incubation with MCF-7 cells. IC50 values of NPs, equivalent drugs, and free drugs are shown in the table.
