As a result, the coating is covalently attached to the substrate, giving superb adhesion and durability.
ABSTRACT--Precursor gels containing covalently incorporated lead thiolate complexes have been prepared using the bifunctional linker molecule, 3-mercaptopropyltrimethoxysilane along with typical sol-gel processing techniques.
Called the covalently linked immunomagnetic separation/ adenosine triphosphate (Cov-IMS/ATP) technique, the portable process uses magnetic beads linked covalently to antibodies that bind FIB.
