MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202611003421 A) filed by Alishba Noor; Aarti Sharma; and Sarita Kumar, Greater Noida, Uttar Pradesh, on Jan. 13, for 'a system and a method for smart phytochemical-regulated silver nanocomposite-based larvicidal control.'
Inventor(s) include Alishba Noor; Aarti Sharma; and Sarita Kumar.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure relates to a system and method for intelligent phytochemical-regulated larvicidal control utilizing a plant-mediated silver nanocomposite derived from an aqueous leaf extract of Tradescantia pallida. The system has three main parts: a processor-controlled plant extract processing module, a nanocomposite synthesis module, and a phytochemical-regulated release module. These parts work together to make spherical silver nanocomposites with a face-centered cubic crystalline structure and a particle size of 15-40 nm. The phytochemicals in the plant extract work as both reducing and functional stabilizing agents. They make a capping layer that controls the release of silver ions and lets the larvicidal activity happen over time. The described method offers prolonged and targeted larvicidal effectiveness against early fourth-instar Aedes aegypti larvae at low concentrations, while reducing acute toxicity and environmental persistence. The system also makes it easier for the nanocomposite to deactivate itself after it has killed larvae. This disclosure presents an environmentally sustainable, low-dose, and technologically sophisticated alternative to traditional chemical larvicides for mosquito vector management."
