Environment-friendly Adhesion and Release Control by Using Ionic Polymer Brushes

Photopatterned polymer brushes promoting cell adhesion gradients.

The ability to spatially control cellular adhesion in a continuous manner on a biocompatible substrate is an important factor in designing new biomaterials for use in wound healing and tissue engineering applications. In this work, a novel method of engineering cell-adhesive RGD-ligand density gradients to control specific cell adhesion across a substrate is presented. Polymer brushes exhibitin...

Supramolecular surface adhesion mediated by azobenzene polymer brushes.

Surface immobilised polymer brushes containing azobenzene units were prepared using a combination of microcontact chemistry and surface-initiated atom transfer radical polymerisation (SI-ATRP). These brushes were investigated using AFM, XPS and UV/vis spectroscopy. It was shown that two surfaces bearing azobenzene brushes can be glued together in the presence of a β-cyclodextrin polymer and hol...

Control of surface properties using fluorinated polymer brushes produced by surface-initiated controlled radical polymerization.

Surface-grafted styrene-based homopolymer and diblock copolymer brushes bearing semifluorinated alkyl side groups were synthesized by nitroxide-mediated controlled radical polymerization on planar silicon oxide surfaces. The polymer brushes were characterized by X-ray photoelectron spectroscopy (XPS), near-edge X-ray absorption fine structure (NEXAFS), and time-dependent water contact angle mea...
