3D Printing Technique Makes Degradable Biomaterials

A stereolithographic technique has been developed for making 3D-printed biomaterials that can undergo controlled degradation. This technique uses noncovalent (ionic) crosslinking and could potentially enable the fabrication of adaptive and stimuli-responsive biomaterials for use in biosensing, drug delivery and tissue engineering applications. Stereolithographic printing typically uses photoactive polymers that link together with covalent bonds — which are strong, but irreversible. A research team from Brown University experimented with using potentially reversible ionic bonds to create 3D printed structures.
