Description

Antifouling Polymer Coating (Zwitterionic/PEG-Based System) is engineered to resist non-specific interactions at biointerfaces by creating a highly hydrated surface layer. The system utilizes PEG or zwitterionic functional groups that strongly bind water molecules, forming a physical and energetic barrier against protein adsorption and cellular attachment.

This material is widely used in biosensors, diagnostics, and biomedical devices where minimizing background noise and improving specificity are critical. It can be applied to a variety of substrates including glass, polymers, metals, and microfluidic devices. Surface density and coating thickness can be tuned to optimize antifouling performance.
