A facile strategy for the modification of polyethylene substrates with non-fouling, bioactive poly(poly(ethylene glycol) methacrylate) brushes

Harm-Anton Klok, Jeffrey Alan Hubbell, Brian Pullin

This manuscript reports a facile strategy for the modification of polyethylene, a widely used biomaterial, with a thin non-biofouling coating that can act as a platform to introduce biochemical cues to control and direct, e.g., cell adhesion and proliferat ...

Design of a high-throughput device for screening surface modification protocols

Karl Gademann

The development of new high performance, ultra-thin organic coatings requires a strategy that has to consider a large number of surface treatment variables such as binding moieties, substrate, and adsorption conditions (e.g. temperature, solvent, concentra ...

Surface modification of PES virus filtration membrane

Claire Roulin

Virus filtration by size exclusion is a robust means of eliminating viruses in blood or pharma products. Porous polymer membranes with a narrow size distribution are used to allow passage of the protein product but retain viruses. The chosen polymer must r ...

Biofunctional and biomimetic polymer brushes prepared via surface-initiated atom transfer radical polymerization

Harm-Anton Klok

Surface-initiated controlled radical polymerization is a powerful strategy to tailor the chemical and physical surface properties of materials. This article highlights recent work from the author's laboratory in which surface-initiated atom transfer radica ...

Cyanobacterial Natural Products for the Inhibition of Biofilm Formation and Biofouling

Karl Gademann

Biofouling is defined by the non-specific attachment of biological material (proteins, carbohydrates, prokaryotic cells and higher organisms) to surfaces upon their exposure to any biological fluid. Biofouling is a serious problem in many areas ranging fro ...
