Amphiphilic 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...

Freezing-induced ordering of block copolymer micelles.

We demonstrate here the ordering of block copolymer micelles by ice templating, below 0 °C. We used this for the preparation of silica monoliths that present an ice-templated macroporosity, combined with a 2D hexagonal mesostructure templated by the addition of P123. We propose a mechanism triggered by the progressive freezing-induced concentration.

Amphiphilic Block Copolymer Micelles for Drug Delivery Vehicles

Amphiphilic block copolymer micelles have been the focus of research for the last decades because of the promising properties as nano size drug delivery vehicles. In polar aqueous milieu, copolymers self assemble into micelle structures which consist of hydrophilic corona and hydrophobic core regions. Space created inside the micelle core can be used for transportation of drug molecules of hydr...

Study of Block Copolymer Micelles as Vehicles for Anticancer Drug

Block copolymer micelles as switchable templates for nanofabrication.

Block copolymer inverse micelles from polystyrene-block-poly-2-vinylpyridine (PS-b-P2VP) deposited as monolayer films onto surfaces show responsive behavior and are reversibly switchable between two states of different topography and surface chemistry. The as-coated films are in the form of arrays of nanoscale bumps, which can be transformed into arrays of nanoscale holes by switching through e...
