The systematic tunability of nanoparticle dimensions through the controlled loading of surface-deposited diblock copolymer micelles.
نویسندگان
چکیده
The continuous tunability of iron oxide nanoparticle dimensions is demonstrated using the pH controlled loading of ferric nitrate from aqueous solution into polystyrene-block-polyacrylic acid reverse micelles deposited on a silicon substrate. Quasi-hexagonally ordered two-dimensional arrays of iron oxide nanoparticles with a systematic tunability of particle heights in the sub-10 nm regime and a constant periodicity are obtained and characterized with atomic force microscopy and x-ray photoelectron spectroscopy.

Drug-loaded and superparamagnetic iron oxide nanoparticle surface-embedded amphiphilic block copolymer micelles for integrated chemotherapeutic drug delivery and MR imaging.
We report on the fabrication of organic/inorganic hybrid micelles of amphiphilic block copolymers physically encapsulated with hydrophobic drugs within micellar cores and stably embedded with superparamagnetic iron oxide (SPIO) nanoparticles within hydrophilic coronas, which possess integrated functions of chemotherapeutic drug delivery and magnetic resonance (MR) imaging contrast enhancement. ...
متن کاملBlock copolymer micelle nanolithography
Au-nanoclusters between 2 and 8 nm in diameter were deposited onto solid substrates in different pattern geometries. The basis of this approach is the self-assembly of polystyrene-b-poly[2-vinylpyridine (HAuCl4)] diblock copolymer micelles into uniform monomicellar films on solid supports such as Si-wafers or glass cover slips. HAuCl4 as metallic precursor or a single solid Au-nanoparticle caus...
متن کاملControlled hydrophobic functionalization of natural fibers through self-assembly of amphiphilic diblock copolymer micelles.
The functionalization of natural fibers is an important task that has recently received considerable attention. We investigated the formation of a hydrophobic layer from amphiphilic diblock copolymer micelles [polystyrene-block-poly(N-methyl-4-vinyl pyridinium iodide)] on natural fibers and on a model surface (mica). A series of micelles were prepared. The micelles were characterized by using c...
متن کاملNear-Critical Micellization for Nanomedicine: Enhanced Drug Loading, Reduced Burst Release
Micelles, a self-assembled formation of diblock copolymer chains, have been shown to have utility for delivery of highly hydrophobic drugs. This is due to their ability to solubilize these drugs into the core of the micelle, thereby increasing the effective dose of drug available for delivery, and to target cancer cells via the enhanced permeation and retention (EPR) effect. In most conventiona...
متن کاملAmphiphilic Block Copolymer Nano-micelles: Effect of Length Ratio of the Hydrophilic Block
Block copolymer nano-micelles are especially important in cancer treatment because of their fine dimensions. In this article, three systems of amphiphilic copolymers with similar lengths and different ratios of the hydrophobic and hydrophilic chains are studied using implicit-solvent coarse-grained molecular dynamics simulations. The factor fphil is defined as the ratio of the number...
