Abstract
|
The model system fluorapatitegelatin allows mimicking the formation conditions on a lower level of complexity compared to natural dental and bone tissues. Here, we report on solid-state NMR investigations to examine the structure of fluorapatitegelatin nanocomposites on a molecular level with particular focus on organicinorganic interactions. Using 31P, 19F, and 1H MAS NMR and heteronuclear correlations, we found the nanocomposite to consist of crystalline apatite-like regions (fluorapatite and hydroxyfluorapatite) in close contact with a more dissolved (amorphous) layer containing first motifs of the apatite crystal structure as well as the organic component. A scheme of the intergrowth region in the fluorapatitegelatin nanocomposite, where mineral domains interact with organic matrix, is presented.
