Cluster Growth Model for Hydroxyapatite
Kazuo Onuma,Atsuo Ito +1 more
TL;DR: In this paper, the authors proposed a cluster growth model where hydroxyapatite grows by selective hexagonal packing of left and right-handed chiral Ca9(PO4)6 clusters 0.8 nm in size.
Journal ArticleDOI
Zinc-releasing calcium phosphate for stimulating bone formation ☆
Atsuo Ito,Haruo Kawamura,Makoto Otsuka,Masako Ikeuchi,Hajime Ohgushi,Kunio Ishikawa,Kazuo Onuma,Noriko Kanzaki,Yu Sogo,Noboru Ichinose +9 more
TL;DR: Findings suggest that the zinc-containing tricalcium phosphate is a biomaterial that has a pharmaceutical effect of promoting bone formation.
Journal ArticleDOI
Materials chemistry: A synthetic enamel for rapid tooth repair
Kazue Yamagishi,Kazuo Onuma,Takashi Suzuki,Takashi Suzuki,Fumio Okada,Junji Tagami,Masayuki Otsuki,Pisol Senawangse +7 more
TL;DR: A dental paste of synthetic enamel that rapidly and seamlessly repairs early caries lesions by nanocrystalline growth, with minimal wastage of the natural enamel is described.
Journal ArticleDOI
Formation and growth of clusters in conventional and new kinds of simulated body fluids
TL;DR: New kinds of SBFs with ion concentrations nearer to those of blood plasma are prepared and the m-SBF is recommended for the assessment of bioactivity of artificial materials as well as the formation of bonelike apatite on various substrates from the viewpoint of stability as wellAs similarity to blood plasma.
Journal ArticleDOI
Direct transformation from amorphous to crystalline calcium phosphate facilitated by motif-programmed artificial proteins
TL;DR: Time-resolved static light-scattering analyses revealed that, in the presence of the protein, amorphous calcium phosphate particles increased their fractal dimension and molecular mass without increasing their gyration radii during a short period before precipitation, indicating heterogeneous growth transformation.
