And method responsive gel for selectively removing target material from the environment

摘要

(57) responsive gel to selectively remove a target substance from [summary] environment is described. Polymer gels reversible response of the three-dimensional, consisting of the junction of at least two with respect to the target material capable of forming a binding site when they approach each other, to bind a target substance. The coupling portion is combined with a responsive polymer components correspond to changes in environmental conditions, is adapted to receive the expansion and volume shrinkage reversible. Polymer gel component has a volume contraction phase transition threshold that is different from the phase transition leap value of volume expansion. The responsive gels, when the polymer gel shrinks in the contracted state phase transition threshold, to allow the binding site to bind the target substance to each other and the coupling portion is to be placed so as to close enough to the target substance is built. When the polymer expands to expanded state in the phase transition threshold, the coupling portion is disconnected from each other. Method of removing a target substance from the environment is also described, to bind the target substance-binding site and has a binding affinity target substance, for the binding site of the polymer gel of the present invention, the coupling portion and to each other including the steps of contacting with the target substance, such that it is sufficiently close to the target, allows the gel is transferred to a contracted state. Method for selectively removing the target material selected from the target material solution, and other target materials are also described. Procedure for changing the environmental conditions, consists of varying the temperature of the gel in the preferred embodiment.
