Description

Surface-Functionalized Hydrogel (PEG-Based Biointerface System) is engineered with functional groups (e.g., NHS, carboxyl, or maleimide) that enable covalent or affinity-based binding to biomolecules, surfaces, and substrates. The PEG backbone provides a non-fouling and biocompatible environment, reducing non-specific adsorption while allowing controlled functionalization.

This material is widely used to modify surfaces for biosensing, diagnostics, and biointerface engineering. It enables immobilization of proteins, antibodies, DNA, or cells on substrates such as glass, polymers, or microfluidic chips. Functional group density and hydrogel properties can be tuned to optimize binding efficiency and specificity.
