Thermoresponsive micropatterned substrates for single cell studies.

PLoS ONE, 2012
We describe the design of micropatterned surfaces for single cell studies, based on thermoresponsive polymer brushes. We show that brushes made of poly(N-isopropylacrylamide) grafted at high surface density display excellent protein and cell anti ...

Polymer Brush Friction in Cylindrical Geometries

Lubricants, 2019
Polymer brushes are outstanding lubricants that can strongly reduce wear and friction between surfaces in sliding motion. In recent decades, many researchers have put great effort in obtaining a clear understanding of the origin of the lubricating ...

CO₂ Capture by Reduced Graphene Oxide Monoliths with Incorporated CeO₂ Grafted with Functionalized Polymer Brushes

Applied Sciences, 2021
The monolithic materials of reduced graphene oxide (rGO) can be used successfully in CO2 adsorption. Here, the incorporation of CeO2 particles with and without polymer brushes grafted from the particles showed that the structural properties could be ...

Impact of solvent quality on tribological properties of polymer brushes

Научно-технический вестник информационных технологий, механики и оптики
Polymer brushes, as modifying coatings, significantly improve the tribological properties of various contacting surfaces. The friction that arises when an external load is applied and the polymer brushes laterally shift relative to each other is ...

Influence of Solutes on Hydration and Lubricity of Dextran Brushes

CHIMIA, 2012
The characteristic lubricity and non-fouling behavior of polymer brushes is critically dependent on the solvation of the polymer chains, as well as the chain–chain interactions.

Cohesiveness tunes assembly and morphology of FG nucleoporin domain meshworks – Implications for nuclear pore permeability [PDF]

, 2013
Nuclear pore complexes control the exchange of macromolecules between the cytoplasm and the nucleus. A selective permeability barrier that arises from a supramolecular assembly of intrinsically unfolded nucleoporin domains rich in phenylalanine-glycine ...
