Insertion of Gold Nanoparticles in Fluid Mesophases: Size Filtering and Control of Interactions
Hydrophobically coated gold nanoparticles have been inserted in swollen surfactant lamellar phases. Insertion of the gold nanoparticles is observed only above a critical hydrophobic thickness that depends on the particle size. Such a system can thus be used as a size filter for hydrophobically coated gold nanoparticles. Above this critical thickness, large amounts of nanoparticles can be inserted, forming a 2D fluid in each lamella. The interaction
