SOLID SURFACE COATED WITH A HYDROPHILIC BIOPOLYMER-REPELLENT OUTER LAYER AND METHOD OF MAKING SUCH A SURFACE |
摘要 |
A solid surface having anionic groups capable of reacting with a polyethylene imine substituted at least in part by at least 50% by weight of a hydrophilic nonionic polymer having a molecular weight within the range from about 400 to about 200,000 is provided with a hydrophilic biopolymer-repellent outer surface layer thereof by reacting such a polyethylene imine substituted by nonionic hydrophilic polymer with anionic groups on the solid surface, in an amount sufficient to produce biopolymer-repellent solid surface, and accordingly having low spontaneous adsorption of proteins and other biopolymers through electrostatic attraction and/or hydrophobic interaction.
