- Аннотация: Spontaneous embedding of gold nanoparticle (NP) aggregates or polyelectrolyte microcapsules modified with NPs in biocompatible hyaluronic acid/poly(L-lysine) films is reported. The NPs were adsorbed in the aggregated state to induce near-IR light absorption. The films functionalized with gold NPs become active in response to a "biologically friendly" near-IR laser at a power of about 20 mW. The activation is characterized by a localized temperature increase in the Film, allowing conversion of light energy to heat into confined volumes. Microcapsules adsorbed onto the film can release its cargo under stimulation with near-IR light because of localized permeability changes in their walls. This work is aimed at layer-by-layer film-based biomedical coatings and active surfaces with light-sensitive features wherein metal NPs and microcapsules are used as active centers or carriers with remote control of functionalities.
