Scheme of nanostructured device production.

Notes: Nanostructured systems can be produced using techniques that intrinsically lead to nanoparticles (silver nanoparticles, liposomes) or evolve from other techniques. Interfacial deposition and nanoprecipitation have evolved from synthetic polyester manufacturing techniques, and solid lipid nanoparticles are derived from liposome production technique. Eventually, new techniques are continuously developed: electrospinning of drug-loaded matrix and drug-loaded nanogels. The last class groups different production strategies and materials: pH-responsive hydrogels, self-assembling systems, and nanodevices based on natural polymers.

Abbreviation: sol, solution.
