MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202511122587 A) filed by Chandigarh University, Mohali, Punjab, on Dec. 5, 2025, for 'root-sensing nano-fertilizer for controlled and sustainable nutrient delivery.'
Inventor(s) include Kirti Babber; and Dr. Yogesh Kumar Ahlawat.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to nano-fertilizer system capable of releasing nutrients on demand in response to plant root exudates 106 and soil pH. The system comprises nutrient-loaded nanocarriers with a biodegradable dual-responsive shell 102 functionalized with root-exudate-sensitive ligands and pH-responsive polymers. A nanozyme catalytic layer accelerates polymer degradation upon biochemical stimulation, while a self-regenerative nutrient reservoir reabsorbs and re-releases ions from the soil for sustained nutrient availability. The outer surface is coated with microbial prebiotics that promote beneficial soil microbes and assist in nanocarrier biodegradation. Nutrient release occurs only under specific biochemical and pH conditions, ensuring targeted and efficient nutrient delivery directly in the rhizosphere. This intelligent, bio-interactive system minimizes nutrient losses, enhances soil fertility, and supports sustainable precision agriculture through synchronized nutrient supply based on real-time plant needs."
