MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202541105973 A) filed by Dr. Jaya T Varkey; Dr. Maria Linsha P L; and Dr. Mariyam Thomas, Cochin, Kerala, on Nov. 2, 2025, for 'antibacterial nanofiber-based filters for portable water purification and a method thereof.'
Inventor(s) include Dr. Jaya T Varkey; Dr. Maria Linsha P L; and Dr. Mariyam Thomas.
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 invention relates to an antibacterial nanofiber filter for water purification comprising electrospun nanofiber membranes and cast nanofilms formed from a homogeneous chitosan/polyvinyl alcohol (PVA) solution mixed with calcium oxide (CaO) nanoparticles derived from biogenic sources. The invention also provides a method of preparation of the nanofibers (10). The blend of chitosan/PVA/CaO is electrospun into nanofiber (10) using a syringe (20) and metallic spinneret (22) to produce membranes that are cut and packed into sachet filter units for water purification. Alternatively, the same blend is cast into a petri dish and dried to form a nanofilm, which is then used in filter sachets. The resulting media leverage CaO's alkalinity and bactericidal activity due to chitosan's antimicrobial functionality and polyvinyl alcohol's ability to reduce microbial load in water, providing low-cost, scalable filtration materials that valorize biowaste and support circular-economy manufacturing."
