摘要： Dynamic polymer surfaces are provided that include alternating micropatterns of adhesive domains and environmental stimuli-responsive repulsive domains, where application of a select environmental stimulus activates polymer structures of the repulsive domains to change conformation with respect to the adhesive domains. The dynamic polymer surfaces are useful for sorting, screening, and enriching target particles (such as cells) in a sample and for culturing and harvesting cells. Products, such as cell culture systems, including the dynamic polymer surfaces are also provided.

摘要： A biocompatible hydrogel has between 0.3% and 30% by weight of dry matter of a copolymer formed at least from acrylamide, chitosan and N,N′-methylenebisacrylamide, as well as a diffusing agent. The diffusing agent is advantageously selected from the group consisting of inert ingredients which have biomechanical properties and active ingredients. A method of manufacturing the hydrogel by copolymerizing, washing, and adding the diffusing agent is provided, as well as a mechanical visco-supplementation system adapted for external or internal use that includes the hydrogel, and an external or internal mechanical visco-supplementation kit including an acrylamide and chitosan copolymer crosslinked with N,N′-methylenebisacrylamide, and a diffusing agent in solid phase or in suspension, the copolymer and the diffusing agent having been previously mixed in the form of a hydrogel during manufacture or being adapted to be mixed extemporaneously to form a hydrogel.
