Journal ArticleDOI
Resorbable bioceramics based on stabilized calcium phosphates. Part II: evaluation of biological response.
TL;DR: In vitro biological testing and preliminary in vivo testing show that the important features of this new biomaterial are a characteristic calcium phosphate phase composition and a unique microporous morphology.
Journal ArticleDOI
Structure and composition of silicon-stabilized tricalcium phosphate
M. Sayer,A. D. Stratilatov,Joel Reid,Lazaro Calderin,Malcolm J. Stott,Xilin Yin,M MacKenzie,Timothy J. N. Smith,Jason A. Hendry,S. Langstaff +9 more
TL;DR: A composition range and crystallographic structure for Si-TCP is proposed and it is proposed that Si(4+) substitutes for P(5+)in the TCP lattice with the average chemical composition of Si- TCP set primarily by the mechanisms available for charge compensation.
Journal ArticleDOI
Resorbable bioceramics based on stabilized calcium phosphates. Part I: rational design, sample preparation and material characterization
TL;DR: Materials have two characteristic features: a phase composition which is a mixture of calcium hydroxyapatite and a silicon stabilized tricalcium phosphate, and a microporous morphology based on inter-connected particles (0.2-1 microm in diameter).
Journal ArticleDOI
Phase formation and evolution in the silicon substituted tricalcium phosphate/apatite system.
TL;DR: The sintering of silicon doped calcium phosphate ceramics prepared from a basic colloidal hydroxyapatite precipitate mixed with silica over 800 degrees C yields a phase mixture of tricalcium phosphate phases (TCP) designated Si-TCP, beta- TCP and a silicon substituted dehydrated apatite (Si-Ap).
Journal ArticleDOI
Antibacterial activity of multilayer silver–copper surface films on catheter material
Robert J. C. McLean,AA Hussain,M. Sayer,Peter J. Vincent,David J. Hughes,Timothy J. N. Smith +5 more
TL;DR: Ag-Cu layered surface films also showed antibacterial activity against Pseudomonas aeruginosa biofilm formation and show great promise in lowering the incidence of device-associated nosocomial infections.
