MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202541133284 A) filed by Niranjan. K. R; Praveen S P; Puviyarasan S; Sakthi Nimalash M S; and Akshaya A, Coimbatore, Tamil Nadu, on Dec. 30, 2025, for 'silver nanoparticle enhancing dye degradation.'
Inventor(s) include Niranjan. K. R; Praveen S P; Puviyarasan S; Sakthi Nimalash M S; and Akshaya A.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a green and eco-friendly method for dye degradation using silver nanoparticles biosynthesized from natural honey. Natural honey functions as both a reducing and stabilizing agent, enabling the conversion of silver ions into silver nanoparticles under controlled pH conditions without the use of toxic chemicals. The biosynthesized silver nanoparticles exhibit enhanced catalytic activity toward the efficient degradation of synthetic dyes in aqueous solutions. Comprehensive characterization of the synthesized nanoparticles is performed using UV-Visible spectroscopy to confirm nanoparticle formation, Fourier Transform Infi'ared (FTI.R) spectroscopy to identify functional groups involved in reduction and stabilization, and Scanning Electron Microscopy (SEM) for morphological analysis and surface topology evaluation, along with electron-based particle size distribution techniques. The developed invention provides a sustainable, cost-effective, and efficient approach for wastewater treatment and environmental remediation applications. Keywords: Silver nanoparticles; Green synthesis; Natural honey; Dye degradation; Wastewater treatment; Biosynthesis; Eco-friendly nanotechnology; Scanning Electron Microscopy (SEM); Catalytic activity; Environmental remediation."
