Abstract
A solid support useful for bioaffinity and ion-exchange separations and enzyme immobilization is provided. The support is based on a non-perfluorocarbon solid carrier core coated with a nonionic fluorosurfactant-coated fluorocarbon interlayer to which a ligand or a binder for the ligand is securely, but reversibly attached through a reactive perfluorocarbon anchor compound. Also provided is a solid support useful for size exclusion separations. Such support is based on a non-perfluorocarbon carrier core coated with a nonionic fluorosurfactant-coated fluorocarbon interlayer.
