MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641050641 A) filed by Mohan Babu University, Tirupati, Andhra Pradesh, on April 21, for 'cinnamomum cassia bark essential oil-derived silver nanoparticle composition.'
Inventor(s) include Dr. S. Muthulingam; Dr. J. Dinesh Babu; Dr. Shaik Ibrahim Khalivulla; Dr. K. P. Greeshma; and Dr. K. Gnana Priya.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a Cinnamomum cassia bark essential oil-derived silver nanoparticle composition exhibiting a distinctive nanoscale architecture and ornamental surface morphology. The composition comprises silver nanoparticles synthesized and stabilized through the use of bioactive constituents present in the essential oil, which act as natural reducing and capping agents. This results in the formation of nanoparticles with controlled size, predominantly spherical or quasi-spherical shape, and a stable bio-organically coated surface. The nanoparticle composition is characterized by a uniform yet naturally varied distribution of particles, forming clustered and granular arrangements that create a visually textured surface pattern. The interaction between the silver nanoparticles and the organic molecules derived from the essential oil leads to a consistent structural configuration with reduced agglomeration and enhanced stability. The surface morphology exhibits nanoscale features such as particle clustering, semi-uniform dispersion, and patterned aggregation, contributing to the unique ornamental appearance of the composition. The design is primarily defined by its surface texture, particle arrangement, and morphological uniformity, rather than functional properties. Variations in particle size and distribution may occur without altering the overall visual impression of the composition. The invention provides a novel, eco-friendly, and aesthetically distinctive nanoparticle-based design, derived from a natural source, suitable for protection under design patent provisions."
