HYDROXYAPATITE – TechConnect Briefs

Microwave-assisted synthesis of bioabsorbable nanoparticles to be used as reinforcement of PLGA in biomedical applications

Colmenares G.J., Ramírez M.E., Ortiz I.C., Hoyos L.M., Universidad Pontificia Bolivariana, CO

Biodegradable polymers have been used in a large number of mass production applications such as packaging, paper coating, fibers, films and other disposable items, as well as in biomedical applications (Kalia & Avérous, 2011). The [...]

Mechanical Properties of a composite material made of HAp nanofibers

Alanis J.R., Velazquez R., Rivera E.M., Universidad Autónoma de Querétaro, MX

Biomaterials based on hydroxyapatite (HAp) are often studied due to the favorable answer presented as a substitute of bone tissue. However, the mechanical properties of these materials have not been studied deep enough. Synthesis of [...]

Preparation and investigation of nano- carbonated hydroxyapatite/polymer composite spongy scaffolds for biomedical applications

Siddiqi S.A., Manzoor F., Azhar U., Jamal A., Tariq M., Anwar M.S., Saleem M., Chaudhry A.A., Rehman I.U., COMSATS Institute of Information Technology, PK

Spongy scaffolds containing nano-Carbonated Hydroxyapatite (nCHA), with composition Ca10(PO4)6-y(CO3)y(OH)2,with y=2,4, were prepared by the lyophilization method. Different polymers, natural gelatin (G), chitosan (CS) and polyvinyl alcohol (PVA), alone or in combination, were used to make [...]

Evolutionary selection of bone mineral hydroxyapatite binding peptide using landscape phage library

Modali S., Abbineni G., Jayanna P., Petrenko V., Mao C., University of Oklahoma, US

Hydroxyapatite [(Ca5(PO4)3OH)2] is a biomineral which is associated with bone proteins to form mineralized extracellular matrix in a mature bone. Using two landscape phage libraries, in which random octa-peptides and nona-peptides are displayed on all [...]

Biological influence of nanofibrous hydroxyapatite-polycaprolactone membrane on human periodontal ligament cell

Kim H.W., Kim T.I., Lee S.J., Ku Y., Rhyu I.C., Chung C.P., Han S.B., Kim H.W., Kim T.I., Seoul National University, KR

This study was performed to evaluate the effect of hydroxyapatite-coated nanofibrous polycaprolactone membrane on proliferation and differentiation of periodontal ligament cell which is necessary for periodontal regeneration. Hydroxyapatite-coated nanofibrous polycaprolactone membrane was fabricated through electrospinning [...]

Synthesis and Synterability of Hydroxyapatite-Coated Zirconia Nanopowders

Bondioli F., Cannillo V., Ferrari A.M., Manfredini T., Università di Modena e Reggio Emilia, IT

Hydroxyapatite (HAP), Ca10(PO4)6(OH)2, is a well-known and a valuable implant material with biocompatibility and bioactive properties. Full utilisation of the unique properties of hydroxyapatite bulk ceramics is, however, possible only after its proper reinforcement, i.e. [...]

Formation of Nano CoFe2O4 Crystallites in Hydroxyapatite

Pon-On W., Tang I.M., Mahidol University, TH

Embedding nano size CoFe2O4 ferrite particles in a hydroxyapatite (HAP) host would make them to better candidates for hyperthermia treatment of cancer. The formation of nano crystallites of CoFe2O4 ferrites in the hydroxyapatite Ca10-3xFe2xCox(PO4)6(OH)2 (where [...]
