MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202521103985 A) filed by Symbiosis International, Pune, Maharashtra, on Oct. 28, 2025, for 'bio-based superabsorbent polymer cryogel comprising carboxymethyl cellulose, moringa oleifera and biochar for biomedical applications.'
Inventor(s) include Ruchi Mishra Tiwari; Snehal; and Pooja Singh.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a bio-based superabsorbent polymer (SAP) cryogel (104) comprising carboxymethyl cellulose (CMC) (101) as a plant-derived polymeric matrix, Moringa oleifera pod powder (102) as a bioactive functional additive, and waste-derived rice husk biochar (103) as a reinforcing component. The components are crosslinked using EDC/NHS chemistry (105) and structured through cryogelation to form a macroporous interconnected network. The developed SAP cryogel exhibits high swelling capacity (109) exceeding 16 g per gram, water uptake (110) of approximately 96%, adequate mechanical strength (111), enhanced biocompatibility (106), cell proliferation support (107), and controlled biodegradability (108). The cryogelation process involves freezing polymer solutions at cryogenic temperatures where ice crystals act as porogens, followed by thawing and lyophilization. The eco-friendly cryogel provides a sustainable alternative to synthetic SAPs for biomedical applications including sanitary products, wound dressings, tissue engineering scaffolds, and agricultural water retention."
