Inventor(s) include Kumari Nandita; Dr. Sanjay Sahay; Dr. Hidyatullah Mir; Dr. Tushar Ranjan; Dr. Manoj Kundu; Dinabandhu Samata; Dr. Kumari Rashmi; and Priyanka Kumari.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "Nanotube-augmented micropropagation method for enhanced regeneration and acclimatization of pineapple plantlets. This invention describes a nanomaterial-augmented protocol for the micropropagation of Ananas comosus (pineapple), employing sonicated Multi-Walled Carbon Nanotubes (MWCNTs) incorporated into stage-specific Murashige and Skoog (MS) media. The protocol enhances in vitro regeneration efficiency, stress tolerance, and post-transfer survival rates. Explants are sterilized using ethanol and mercuric chloride, followed by culture in MWCNT-enriched media optimized for callus induction (1.0 mg/L BAP), shoot organogenesis (0.5 mg/L BAP), and rooting (2.0 mg/L IBA). MWCNTs are uniformly dispersed through controlled sonication, enabling improved nutrient absorption and hormonal responsiveness. Regenerated plantlets are acclimatized ex vitro in cocopeat, promoting robust root development and minimizing transplant shock. The invention provides a reproducible, scalable system applicable to commercial and research-based tissue culture operations, offering substantial improvements over conventional pineapple propagation methods."
