MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202641001427 A) filed by Laniya Nasrin K; and Reshmi Krishna A, Malappuram, Kerala, on Jan. 6, for 'an antimicrobial coated catheter.'
Inventor(s) include Laniya Nasrin K; and Reshmi Krishna A.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The present invention provides a urinary catheter comprising a catheter body and an antimicrobial coating solution disposed on a surface of the catheter body. The antimicrobial coating comprises PEGylated zinc oxide nanoparticles loaded with a bacteriocin-cyclodextrin complex, wherein the antimicrobial coating provides sustained release of antimicrobial agents. The PEGylated zinc oxide nanoparticles have a particle size of 50-100 nm. The bacteriocin-cyclodextrin complex comprises Nisin Z-Cyclodextrin complex that improves solubility and stability of Nisin Z for prolonged bioactivity. The antimicrobial coating is applied by a dip-coating process and demonstrates biofilm inhibition against E. coli and S. aureus. Release of the antimicrobial agents follows Korsmeyer-Peppas model kinetics with sustained release continuing for at least 30 days. The antimicrobial coating enhances surface hydrophilicity with a water contact angle reduced to approximately 40 and is biocompatible according to ISO 10993-5 cytotoxicity standards."
