Multifunctional hydroxyapatite and poly(D,L-lactide-co-glycolide) nanoparticles for the local delivery of cholecalciferol
(Elsevier, 2013)
Cholecalciferol, vitamin D3, plays an important role in bone metabolism by regulating extracellular levels of calcium. Presented here is a study on the effects of the local delivery of cholecalciferol (D3) using nanoparticulate ...
Ultrasonic spray pyrolysis of surface modified TiO2 nanoparticles with dopamine
(Materials Chemistry and Physics, 2013)
Spherical, submicronic TiO2 powder particles were prepared in the low temperature process of ultrasonic spray pyrolysis (150 °C) by using as a precursor aqueous colloidal solutions consisting of surface modified 45 Å TiO2 ...
DUV fluorescence bioimaging study of the interaction of partially reduced graphene oxide and liver cancer cells
(IOP Publishing, 2018)
The interaction of partially reduced graphene oxide (prGO) and Huh7.5.1 liver cancer cells was investigated by means of DUV fluorescence bioimaging. The prGO sample was obtained by the reduction (to a certain extent) of ...
Spherical assemblies of titania nanotubes generated through aerosol processing
(Elsevier, 2015)
We report on the possibility to build hierarchically organized three-dimensional (3D) titania spherical particles having high surface-to-volume-ratio, by aerosol processing of nanotubular building blocks. Morphology and ...
Selective anticancer activity of hydroxyapatite/chitosan-poly(d,l)-lactide-co-glycolide particles loaded with an androstane-based cancer inhibitor
(Elsevier, 2016)
In an earlier study we demonstrated that hydroxyapatite nanoparticles coated with chitosan-poly(d,l)-lactide-co-glycolide (HAp/Ch-PLGA) target lungs following their intravenous injection into mice. In this study we utilize ...
Zirconium dioxide nanopowders with incorporated Si4+ions asefficient photocatalyst for degradation of trichlorophenol usingsimulated solar light
(Elsevier, 2016)
We present a hydrothermal method for synthesis of zirconia nanopowders: pure and with incorporatedSi4+ions. Zirconyl chloride and tetraethyl orthosilicate were used as precursors. As prepared powderswere annealed at 600◦C ...
The effect of the androstane lung cancer inhibitor content on the cell-selective toxicity of hydroxyapatite-chitosan-PLGA nanocomposites
(Elsevier, 2018)
An androstane (17β-hydroxy-17α-picolyl-androst-5-en-3β-yl-acetate (derivative A)) cancer inhibitor was successfully captured in a carrier made of nano-sized hydroxyapatite (HAp) coated with chitosan-PLGA polymer blends ...
Effect of PEO molecular weight on sunlight induced photocatalytic activity of ZnO/PEO composites
(Elsevier, 2016)
ZnO spheroidal nanoparticles, synthesized by microwave processing, were used for preparation of composites with polyethylene oxide (PEO). The phase purity and crystal structure of the composites were investigated by X-ray ...
Thermal crystallization of amorphous calcium phosphate combined with citrate and fluoride doping: a novel route to produce hydroxyapatite bioceramics
(Royal Society of Chemistry, 2021)
Amorphous calcium phosphate (ACP) is a material of high interest for dentistry, orthopedics, and other biomedical sectors. Being intrinsically metastable, the process of transformation of ACP into a crystalline phase upon ...
Surface modification of submicronic TiO2 particles prepared by ultrasonic spray pyrolysis for visible light absorption
(Amsterdam : Springer Netherlands, 2012)
Spherical, submicronic TiO2 assemblage with high specific surface area and controllable phase composition was prepared in the process of ultrasonic spray drying/pyrolysis in a wide temperature range (150–800 °C) by using ...
