Two-Dimensional Controlled Syntheses of Polypeptide Molecular Brushes via N-Carboxyanhydride Ring-Opening Polymerization and Ring-Opening Metathesis Polymerization. [PDF]
, 2017 Well-defined molecular brushes bearing polypeptides as side chains were prepared by a "grafting through" synthetic strategy with two-dimensional control over the brush molecular architectures.

Functionalized Antifouling Polymer Brushes for Biospecific Surfaces
Advanced Materials InterfacesBiosensors have become integrated into our lives. Current technology requires biosensors not only to have high sensitivity but also to have high specificity for one target, while repelling all other molecules and materials in the biological medium. These

Highly Stretchable, Adhesive, Biocompatible, and Antibacterial Hydrogel Dressings for Wound Healing
Advanced Science, 2021 Treatment of wounds in special areas is challenging due to inevitable movements and difficult fixation. Common cotton gauze suffers from incomplete joint surface coverage, confinement of joint movement, lack of antibacterial function, and frequent ...

Adaptive coatings based on polyaniline for dynamic pH sensing in micro-fluidic devices [PDF]
, 2011 Polymer brushes based on the conducting polymer polyaniline were synthesized on the interior of micro-capillaries and micro-fluidic channels to study the influence of these brushes on solvent flow through a confined space.

Compression of finite size polymer brushes
, 1998 We consider edge effects in grafted polymer layers under compression. For a semi-infinite brush, the penetration depth of edge effects $\xi\propto h_0(h_0/h)^{1/2}$ is larger than the natural height $h_0$ and the actual height $h$.

Brushes of semiflexible polymers in equilibrium and under flow in super-hydrophobic regime [PDF]
, 2015 We performed molecular dynamics simulations to study equilibrium and flow properties of a liquid in a nano-channel with confining surfaces coated with a layer of grafted semiflexible polymers.

Molecular Transport within Polymer Brushes: A FRET View at Aqueous Interfaces
Molecules, 2022 Molecular permeability through polymer brush chains is implicated in surface lubrication, wettability, and solute capture and release. Probing molecular transport through polymer brushes can reveal information on the polymer nanostructure, with a ...

Combined experimental and simulation studies of crosslinked polymer brushes under shear [PDF]
, 2018 We have studied the effect of crosslinking on the tribological behavior of polymer brushes using a combined experimental and theoretical approach. Tribological and indentation measurements on poly(glycidyl methacrylate) brushes and gels in the presence ...
