Covalently bound spiropyrans on surfaces produced a wettability change of 11[degrees] to 14[degrees] [17] on flat surfaces and about 22[degrees] [20] on structured surfaces such as silicon nanowires.
Amine groups can covalently bond with a variety of polymers, including polycarbonates, polyesters, acrylics, nylons, polyether ether ketones, polysulfones, polyvinylalcohol and polyimides.
9,254,254 B2; Johnson & Johnson has patented a composition that is comprised of a continuous water phase; a discontinuous oil phase, homogeneously distributed in said water phase, that is comprised of a polymer composition comprising a sunscreen agent with a linear, ultraviolet radiation absorbing polyether that has a covalently bound UV-chromophore and comprises a backbone having glyceryl repeat units; and an oil-in-water emulsifier component comprising an anionic oil-in-water emulsifier and a nonionic oil-in-water emulsifier having an alcohol functional group; and the linear, ultraviolet radiation absorbing polyether is present in an amount effective to provide an SPF of 10 or greater.
Whey protein was conjugated either covalently or electrostatically with gellan, and spread on the air-water interface formed on a Langmuir trough.
It was suggested that hydroxyl groups of PUA can not only engage in the intramolecular and/or intermolecular hydrogen bonding, but also form covalently crosslinked networks with polyisocyanate in their films.
They can be further modified by covalently functionalizing the outside of the tube with different atoms or molecules.
Integrating advances in cell biology, chemistry, physics, materials science, and nanoscience, fifteen papers describe the various methods used to covalently engineer cell membranes, transfer protein to a cell surface, bind biotin to a cell surface, modify cell surface architecture with enzymes, and efficiently target transplanted cells to diseased tissues.
