Conformational Change of Bioinspired Polymer Brushes Caused by Specific Capture of Heavy Metal Ion.
To clean up soil and water contaminated with hazardous contaminants using plants, called phytoremediation, relies on the ability of plants to concentrate contaminants from the environment and to detoxify with aid of a protein, phytochelatin (PhyCh) . For example, the dissociation constant of PhyCh to Cd2+ is Kd ~ 10−13 M, which is more than 10 orders of magnitude lower than the commercially used crown ether (Kd ~ 10−2 M). The main aim of the proposed project is to gain deeper insights into conformational changes of PhyCh-inspired polymer brushes at the solid/iquid interface. PhyCh-inspired polymers are grafted onto the surface of a supported membrane via biotin-neutravidin crosslinkers, which enables the precise control of lateral density of polymer brushes. Specular neutron reflectivity experiments at SuperADAM with an outstanding resolution in q enables us to sensitively detect subtle changes in the thickness, density, and roughness of polymer brushes in the presence of monovalent cations (e.g. Na+, K+) and divalent cations (Ca2+, Cd2+, etc.)
