MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202541123899 A) filed by Saveetha Institute Of Medical And Technical Sciences, Chennai, Tamil Nadu, on Dec. 9, 2025, for 'bioadhere.'
Inventor(s) include Palati Sinduja; and Deepak Nallaswamy Veeraiyan.
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 introduces BioAdhere, a novel, sustainable, and cost-effective slidecoating formulation designed to improve tissue adhesion in histopathology and immunohistochemistry. Conventional coating agents such as po l y-L-lysine and gelatin, though effective, are expensive, have limited shelf stability, and may occasionally interfere with staining procedures. The present invention utilizes a simple aqueous solution of com starch as a natural adhesive, providing a biocompatible and biodegradable alternative that ensures strong tissue retention on glass slides during sectioning, staining, and antigenretrieval processes. The formulation is prepared by dispersing 1-3% (w/v) com starch powder in distilled water, followed by gentle heating to 80-90 C until a translucent viscous solution forms. Upon cooling, the solution is applied as a thin film onto clean glass slides and air-dried, producing a uniform, transparent coating. Experimental evaluation demonstrated that BioAdhere-coated slides exhibit excellent tissue adherence, even after multiple hydration and staining cycles, with no evidence of section detachment or folding. Optical clarity and staining compatibility were confirmed for routine hematoxylin and eosin (H&E) and immunohistochemical (IHC) procedures, without background artifact formation. The formulation is non-toxic, easy to prepare, and requires no specialized equipment, with a per-slide cost of less than ?0.50. BioAdhere thus represents a practical, reproducible, and eco-friendly innovation that addresses a critical need for affordable and sustainable laboratory materials, particularly in low-resource diagnostic and teaching settings."
