|Title:||Effect of microgravity on Ca mineral crystallization and implications for osteoporosis in space||Authors:||Liu, X.Y.||Issue Date:||19-Nov-2001||Citation:||Liu, X.Y. (2001-11-19). Effect of microgravity on Ca mineral crystallization and implications for osteoporosis in space. Applied Physics Letters 79 (21) : 3539-3541. ScholarBank@NUS Repository. https://doi.org/10.1063/1.1415047||Abstract:||A study of the effect of microgravity on biomineralization/reminerali/ation by considering Ca mineral nucleation under gravity and microgravity is presented. The structure of human bone is determined to a large extent by the turnover of the bone, which included nucleation of biominerals adjacent to biosubstrates. Heterogeneous nucleation will promote a compact bone structure, whereas homogeaneous nucleation will lead to a porous bone structure. Our experimental results show that microgravity will suppress convection, and consequently promote homogeneous-like nucleation during biomineralization/remineralization. This may explain the formation of the porous bone structure under microgavity condition. © 2001 American Institute of Physics.||Source Title:||Applied Physics Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/96321||ISSN:||00036951||DOI:||10.1063/1.1415047|
