Abstract

A biodegradable and biocompatible three dimensional construct comprising a combination of a nano silicate (e.g., laponite) and two different polymers, the two polymers each individually providing at least one covalently linked polymer chain and at least one ionically linked polymer chain, the polymeric chains forming a dual strengthening intertwined polymeric system. The constructs demonstrate improved mechanical and strength properties, while the bioinks provide a material having superior printability characteristics suitable for printing a three dimensional biodegradable construct having an aspect ratio of greater than 2.0. The bioink may also comprise cells or combinations of cells. Methods of using the constructs and bioinks for wound healing preparations and tissue regeneration are also provided.
