Preparation of bonelike apatite composite for tissue engineering scaffold
A novel sponge composed of a poly (lactic acid) composite skeleton covered with bonelike apatite (b-HA) was produced via a particleleaching technique combined with a biomimetic processing. The sponge has a large porosity of w75% with large-sized pores and shows mechanical ductility. After incubation of human osteoblasts for 7 days, numerous cells attached to the surface of the skeleton, which w...
متن کاملComposite coating of bonelike apatite particles and collagen fibers on poly L-lactic acid formed through an accelerated biomimetic coprecipitation process.
Collagen and apatite were coprecipitated as a composite coating on poly L-lactic acid (PLLA) in an accelerated biomimetic process. The incubation solution contained collagen (1 g/L) and simulated body fluid with 5 times inorganic ionic concentrations as human blood plasma. The coating formed on PLLA films and scaffolds after a 24-h incubation was characterized by using energy-dispersive X-ray s...
متن کاملPLLA scaffolds with biomimetic apatite coating and biomimetic apatite/collagen composite coating to enhance osteoblast-like cells attachment and activity
Novel scaffolds composed of poly(L-lactic acid) (PLLA) skeleton covered with bonelike apatite or apatite/collagen composite were produced via a combined phase-separation technique and an accelerated biomimetic coating process. Saos-2 osteoblast-like cells were used to evaluate the cellular behaviors on these biomimetic coatings. Cell morphologies on the surfaces of PLLA scaffolds, PLLA scaffold...
متن کاملNovel ammonia sensor based on polyaniline/polylactic acid composite films
We propose a new type of ammonia sensor based on composite film between polyaniline (emeraldine base) dissolved in dimethylformamide, and poly(DL-lactic) acid dissolved in chloroform. The two solutions were mixed in weight ratio of the components 1:1 and cast on Al2O3 substrate, on which silver electrodes were deposited previously. The active layer structure and morphology were examined by atom...
متن کاملBiorefinery lignin as filler material in polylactic acid composite
In natural world, lignin is unique and the most abundant renewable carbon source after cellulose, therefore, more applications of adding commercial value of lignin are needed. Polylactic acid (PLA), which has the second highest consumption of bioplastic in the world, is a biodegradable composite with widely application in industry. A filler adding into PLA can decrease the cost of the composite...
