    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

Abstract We report the design, production and characterization of a biosynthetic asymmetric triblock copolymer which consists of one collagen-like and one cationic block spaced by a hydrophilic random coiled block. The polymer associates into micelles when a polyanion is added due to the electrostatic interaction between the cationic block and the polyanion. The collagen-like block self-assembles into thermo-responsive triple helices upon cooling. When both end blocks are induced to self-assemble, a physical gel is formed via thermo-responsive association of the charge-driven micelles. The self-assembly of both end blocks and the effects of salt and temperature thereon were characterized by light scattering and rheology
