Researchers at University of Munster Have Reported New Data on Supramolecular Research (Polymer Brushes Exhibiting Versatile Supramolecular Interactions Grown by Nitroxide-Mediated Polymerization and Structured via Microcontact Chemistry)

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Supramolecular Research. According to news reporting out of Munster, Germany, by NewsRx editors, research stated, "Functionalization of metal, glass, and semiconductor substrates with polymers and nanoparticles is a key challenge for surface-based material science. Such substrates have the potential to find widespread application in optical and electronic devices, microarrays, and materials for information storage."

Our news journalists obtained a quote from the research from the University of Munster, "We report sitespecific immobilization of nitroxide-mediated polymerization initiators via microcontact chemistry employing thiol ene click chemistry on glass-supported alkene-terminated self-assembled monolayers. The polymer initiator covered substrates are used for preparation of poly(styrene) and poly(acrylate) brushes with defined and tunable brush thicknesses. Brush thickness dependent site-specific protein adsorption of streptavidin and concanavalin A on structured polystyrene brushes is reported. Poly(styrene) brushes with a thickness of 40 nm or larger showed protein repellence whereas brushes below 15 nm thickness reveal protein adhesive properties."

According to the news editors, the research concluded: "We also disclose the site selective host guest assisted immobilization of beta-cyclodextrin-coated silica nanoparticles a liposomes modified with amphiphilic beta-cyclodextrin onto adamantane-functionalized poly(acrylate) immobilization of these supramolecular colloids via the multivalent hydrophobic inclusion complex of adamantane can be readily verified by fluorescence microscopy imaging, atomic force microscopy, microbalance with dissipation monitoring."
