Apatite-forming ability of bioactive poly(l-lactic acid)/grafted silica nanocomposites in simulated body fluid.

Bioactive PLLA/surface-grafted silica (g-SiO₂) nanocomposite scaffolds were fabricated by solid-liquid phase separation method. And solid PLLA/g-SiO₂ nanocomposite films were prepared by solution casting method. A series of parallel tube-like morphology and internal ladder-like structure of PLLA/g-SiO₂ nanocomposite scaffolds were observed by SEM. The formation of bone-like apatite in the simul...

In vitro evaluation of apatite/wollastonite glass–ceramic nano biocoatings on 316 alloys by plasma-sprayed

Among bioactive ceramics, the apatite/wollastonite (A/W) glass ceramic, containing apatite and wollastonite crystals in the glassy matrix, has been largely studied because of good bioactivity and used in some fields of medicine, especially in orthopedics and dentistry. However, medical applications of bioceramic are limited to non-load bearing applications because of their poor mechanical prope...

Bioresorbability Evaluation of Hydroxyapatite Nanopowders in a Stimulated Body Fluid Medium

     The bone mineral consists of tiny hydroxyapatite (HA) crystals in the nanoregime. Nanostructured HA is also expected to have better bioactivity than coarser crystals. This paper reports on the in vitro evaluation of bone like HA nanopowders. The prepared HA nanopowder was characterized for its phase purity, chemical homogeneity and bioactivity. Fourier transform infrared (FT-IR) s...

Growth of a bonelike apatite on chitosan microparticles after a calcium silicate treatment.

Bioactive chitosan microparticles can be prepared successfully by treating them with a calcium silicate solution and then subsequently soaking them in simulated body fluid (SBF). Such a combination enables the development of bioactive microparticles that can be used for several applications in the medical field, including injectable biomaterial systems and tissue engineering carrier systems. Ch...
