  12. A Solid State NMR Investigation of Poly (ADP-ribose) and Its Involvement in Tissue Calcification

    The mechanisms of bone and vasculature biomineralisation are not fully understood. It is unclear how the calcium and phosphate ions are concentrated at the calcification site, and how the composition and structure of the mineral phase changes during maturation. This work aims to use solid state NMR …
