This study investigates how storage conditions affect the stability and bioanalytical performance of antifouling poly(carboxybetaine acrylamide) (pCBAA) brushes. Using ellipsometry, IR spectroscopy, SPR, and other methods, we show that pCBAA brushes retain their antifouling properties and biorecognition capacity over time, making them highly reliable for biosensing. Our findings address key challenges in the long-term stability of antifouling coatings for applications in industry and research.
Description
Antifouling pCBAA brushes were stored under various conditions (dry, freezing, and aqueous) for an extended period. They were characterized before and after storage using surface-sensitive techniques to assess their long-term stability, antifouling performance, and functional properties related to biosensing.
