Nano-sized materials possess uniqueness in their properties and designs as compared to their bulk counterparts. For this reason, they have attracted a great deal of attention from the scientific community. Nanocomposite is a composition having a dispersed material that has one or more dimensions, such as length, width and thickness, in the nanometer size range. The nano-sized materials have eme...

Background & Aims: Aflatoxin M1 is one of the most important toxins present in milk and the product of aflatoxin B1 metabolism in liver microsomes. The aim of this project was to study the aflatoxin M1 adsorption ability of polystyrene-hydroxyapatite nanocomposite. Methods: First, the probability of aflatoxin M1 adsorption by the nanocomposite was evaluated us...

BACKGROUND The aim of this study was to evaluate the interaction of bioactive and biodegradable poly (lactide-co-glycolide)/bioactive glass/hydroxyapatite (PBGHA) and poly (lactide-co-glycolide)/bioactive glass (PBG) nanocomposite coatings with bone. MATERIALS AND METHODS Sol-gel derived 58S bioactive glass nanoparticles, 50/50 wt% poly (lactic acid)/poly (glycolic acid) and hydroxyapatite na...

objective(s): the current study reports the production and biocompatibility evaluation of a ternary nanocomposite consisting of ha, pla, and gelatin for biomedical application.materials and methods: hydroxyapatite nanopowder (ha: ca10(po4)6(oh)2) was produced by burning the bovine cortical bone within the temperature range of 350-450 oc followed by heating in an oven at 800. synthesis of the te...

poly (lactide-co-glycolide)/bioactive glass/hydroxyapatite (pbgha) and poly (lactide-co-glycolide)/ bioactive glass (pbg) nanocomposite coatings with bone. materials and methods: sol-gel derived 58s bioactive glass nanoparticles, 50/50 wt% poly (lactic acid)/poly (glycolic acid) and hydroxyapatite nanoparticles were used to prepare the coatings. the nanocomposite coatings were characterized by ...

background: titanium (ti) implants are commonly coated with hydroxyapatite (ha). however, ha has some disadvantages such as brittleness, low tensile strength and fracture toughness. it is desirable to combine the excellent mechanical properties of zro2 and the chemical inertness of al2o3 with respect to the purpose of this project which was coating ti implants with ha-zro2-al2o3 to modify the s...

An opaque, white chitosan/ Hydroxyapatite nanocomposite was prepared by a simple blend method. Morphology, pore size and dispersion of nano-hydroxyapatite in chitosan matrix were visualized using SEM images. The FTIR with EDX analysis confirmed the bony apatite layer formed on outside composite. Porosity measurements water uptake studies evaluated which revealed maximum porosity 80% to 92% chit...

This study focuses on the use of bio-nanocomposite microspheres, consisting of carbonated hydroxyapatite (CHAp) nanospheres within a poly(L: -lactide) (PLLA) matrix, to produce tissue engineering (TE) scaffolds using a modified selective laser sintering (SLS) machine. PLLA microspheres and PLLA/CHAp nanocomposite microspheres were prepared by emulsion techniques. The resultant microspheres had ...
