India, Aug. 25 -- Researchers at the Birla Institute of Technology and Science (BITS) Pilani, K.K. Birla Goa Campus, have developed a pharmaceutical polymer-based hydrogel for 3D printing using extrusion-based method which has the potential to be used for skin tissue engineering and customised drug delivery.

The study explores the use of pharmaceutical grade polymers, such as starch, maltodextrin and sodium alginate, to create hydrogels that display the desired properties needed to be 3D printed. The method could help to solve some of the issues with traditional bioinks: material variability, safety, high costs, and regulatory approvals.

The researchers formulated a hydrogel designed to exhibit the flow and recovery properties necessary...
