MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202641008231 A) filed by Srm Institute Of Science And Technology; and Easwari Engineering College, Chennai, Tamil Nadu, on Jan. 28, for 'eco-friendly green synthesis of zno nanoparticles from costus igneus flower extract for efficient glucose sensing.'
Inventor(s) include Dr. K. Hema; Dr. K. Yuvasri; and Dr. G. Usha Nandhini.
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 green synthesis method for the preparation of zinc oxide (ZnO) nanoparticles using an aqueous extract of Costus igneus flowers as a reducing and stabilizing agent, and to the use of the synthesized ZnO nanoparticles in the fabrication of electrochemical glucose sensors. The method comprises preparing an aqueous flower extract of Costus igneus, reacting it with a zinc precursor under controlled pH and temperature to form ZnO nanoparticles, followed by isolation and calcination. The resulting nanoparticles exhibit enhanced biocompatibility, stability, and surface functionalization due to phytochemicals from the flower extract, enabling sensitive and selective detection of glucose when integrated onto a suitable electrode substrate and operated as a non-enzymatic glucose sensor. The invention provides a low-cost, eco-friendly alternative to conventional chemical synthesis routes and enables the development of green glucose sensing devices."
