Interfacial Ca2+ environments in nanocrystalline apatites revealed by dynamic nuclear polarization enhanced 43Ca NMR spectroscopy

Interfacial Ca2+ environments in nanocrystalline apatites revealed by dynamic nuclear polarization enhanced 43Ca NMR spectroscopy

Solid-state NMR can in principle be used to study calcium environments in biomaterials such as bones/teeth, but43Ca lacks receptivity. Here the authors present an approach to acquire 43Ca data for hydroxyapatite at its natural isotopic abundance, distinguishing between core and surface Ca sites.
