You can mend a broken heart this Valentine’s Day now that researchers invented a new hydrogel that can be used to heal damaged heart tissue and improve cancer treatments. University of Waterloo chemical engineering researcher Dr. Elisabeth Prince teamed up with researchers from the University of Toronto and Duke University to design the synthetic material made using cellulose nanocrystals, which are derived from wood pulp. The material is engineered to replicate the fibrous nanostructures and properties of human tissues, thereby recreating its unique biomechanical properties. …Prince’s research is unique as most gels currently used in tissue engineering or 3D cell culture don’t possess this nanofibrous architecture. Prince’s group uses nanoparticles and polymers as building blocks for materials and develops chemistry for nanostructures that accurately mimic human tissues.
