Researchers in Finland have come up with a new application for well-known materials known as bisphosphonates that includes a possible role for drug delivery. The material, which is known as a treatment for bone-related diseases such as osteoporosis, also forms a gel that could be used to improve the overall function of bone tissue and act as a scaffold for the cells there, according to a new study from the University of Jyväskylä and the University of Eastern Finland. The "supramolecular" gels form a network that can change forms after implantation, a characteristic that could play a part in drug delivery systems. More
