MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541122190 A) filed by Vellore Institute Of Technology, Vellore, Tamil Nadu, on Dec. 4, 2025, for 'methacrylated fruit polysaccharide biomaterial ink for 3d bioprinting.'
Inventor(s) include Dr. Amit Kumar Jaiswal; Shail Shikhar Srivastava; and Aditya Kadam.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure provides a biomaterial ink composition for three-dimensional bioprinting that includes a methacrylated fruit polysaccharide having methacrylate functional groups, 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) as a crosslinker, and a photoinitiator. The composition exhibits a dual crosslinking mechanism combining chemical crosslinking via the EDC and photocrosslinking via the methacrylate functional groups. The composition exhibits shear-thinning properties suitable for extrusion-based three-dimensional bioprinting. The disclosure also provides a method (100) for preparing the biomaterial ink composition that includes extracting (2) a fruit polysaccharide from fruit pulp using hot water extraction, methacrylating the fruit polysaccharide with methacrylic anhydride to introduce photocrosslinkable methacrylate groups, combining the methacrylated fruit polysaccharide with EDC crosslinker and a photoinitiator to form a biomaterial ink formulation, performing dual crosslinking (365) by chemical crosslinking via the EDC followed by UV photocuring, and producing a biomaterial ink with shear-thinning properties suitable for three-dimensional bioprinting."
