MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202641008790 A) filed by Vellore Institute Of Technology, Vellore, Tamil Nadu, on Jan. 28, for 'a metal-crosslinked polymer coating for ceramic substrates and a method thereof.'
Inventor(s) include Gayathri S S; Soumalya Mukherjee; and Dr. Sunita Nayak.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a metal-crosslinked polymer coating for ceramic substrates and a method for forming the same. The coating comprises a polydopamine polymer matrix formed by oxidative polymerisation of dopamine, wherein copper ions are coordinated with catechol and quinone functional groups of the polydopamine to form a metal-polymer crosslinked network adhered to a ceramic substrate. Molecular interaction of dopamine with serum proteins is illustrated with reference to globulin (100) and albumin (200), demonstrating surface protein affinity. Chemical formation and metal coordination of the coating are confirmed through FTIR analysis (300). Antibacterial functionality of the polydopamine-copper compositions against E. coli and S. aureus is demonstrated in (400). The coating is uniformly formed on ceramic scaffolds (500) without altering structural integrity and exhibits enhanced protein adsorption behaviour, as indicated by residual protein concentration analysis (600). The invention further relates to ceramic articles comprising the metal-crosslinked polymer coating."
