We report on ‘optical force stamping’ lithography, a new approach that employs optical forces on single nanoparticles and allows for parallel nanoparticle printing with precision at least 5× better than the diffraction limit of the laser wavelength.
Cross-linked polystyrene nanodisks were prepared by controlled polymerization of styrene and divinylbenzene in the interior of bicelles, discoidal lipid aggregates. Aggregation behavior of polymer nanodisks was studied in water, organic solvents, and solid phase. Nanodisks form stable dispersions in aqueous solutions of surfactants, such as sodium dodecyl sulfate (SDS). Varying SDS/nanodisk ratio...
Gold nanoparticle-loaded liposomes can serve as important biophysical and biochemical tools. A rapid, green, one-step synthetic method has been used for direct and controlled loading of gold nanoparticles onto liposomes. The effects of various synthetic parameters on nanoparticle loading as well as on optical properties of the liposome-anchored nanoparticles are discussed. Gold nanoparticle-loaded...
