MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202621000183 A) filed by Romil Champak Dagha, Nallasopara, Maharashtra, on Jan. 2, for 'a photomediated process for rapid biosynthesis of silver nanoparticles from the halophilic bacteria vreelandella venusta.'
Inventor(s) include Romil Champak Dagha; Komal Kumari; and Prof. Tejashree V. Shanbhag.
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 biosynthesis of silver nanoparticles (Bio-AgNPs) using microorganisms is an emerging approach in nanotechnology; however, conventional biological methods are often limited by prolonged synthesis times. The present invention relates to a photomediated biological process enabling rapid biosynthesis of silver nanoparticles within approximately 10 minutes under natural sunlight. The process employs an intracellular extract derived from the halophilic bacteria Vreelandella venusta as a reducing and stabilizing agent for silver ions. The biosynthesised silver nanoparticles were characterised using UV-visible spectroscopy, transmission electron microscopy (TEM), field-emission scanning electron microscopy (FEG-SEM), energy-dispersive X-ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FTIR), dynamic light scattering (DLS), X-ray diffraction (XRD), and zeta potential analysis. UV-visible spectroscopy indicated a characteristic surface plasmon resonance peak at approximately 430 nm. The nanoparticles were predominantly spherical, with sizes ranging from approximately 20-60 nm. The Bio-AgNPs were further evaluated to demonstrate functional utility through in vitro biological assays."
