Synthesis and Characterization of Hydroxyapatite/Fullerenol Nanocomposites
(Journal of Nanoscience and Nanotechnology, 2015)
Fullerenols are polyhydroxylated, water soluble derivatives of fullerene C60, with potential application in medicine as diagnostic agents, antioxidants or nano drug carriers. This paper describes synthesis and physical ...
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 ...
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 ...
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 ...
Poly(D,L-lactide-co-glycolide)/hydroxyapatite core-shell nanospheres. Part 1: A multifunctional system for controlled drug delivery
(Colloids and Surfaces B: Biointerfaces, 2011)
Biodegradable poly(D,L-lactide-co-glycolide) (PLGA) and bioactive hydroxyapatite (HAP) are selected for the formation of a multifunctional system with the specific core-shell structure to be applied as a carrier of a drug. ...
Chitosan oligosaccharide lactate coated hydroxyapatite nanoparticles as a vehicle for the delivery of steroid drugs and the targeting of breast cancer cells
(Royal Society of Chemistry, 2018)
Low targeting efficiency and fast metabolism of antineoplastic drugs are hindrances to effective chemotherapies and there is an ongoing search for better drugs, but also better carriers. Steroid derivatives, 3β-hydroxy-1 ...
Properties of Hydroxyapatite-Based Biomaterials Important for Interactions with Cells and Tissues
(Springer International Publishing, 2023)
Mammal bone tissue is mainly composed of an inorganic component consisting of calcium phosphate (CaPCalcium phosphateCaP) ceramics, predominantly calcium hydroxyapatiteCalcium phosphatecalcium hydroxyapatite (HAp)Calcium ...
Synthesis and Characterization of Hydroxyapatite-Collagen Biocomposite Materials
(Trans Tech Publications, Ltd., 2003)
Hydroxyapatite-collagen composite is a prosperous biomaterial in reconstructive surgery for the reparation of defects within human hard tissue. Within this research, three-dimensional blocks of HAp/collagen composite ...
The influence of hydroxyapatite modification on the cross-linking of polydimethylsiloxane/HAp composites
(Elsevier, 2004)
Hydroxyapatite (HAp) was modified by the action of various hydrophobic agents based on silicon-containing compounds. The influence of the type of applied agent on the thermodynamic and kinetic parameters of the cross-linking ...
Calcium Hydroxyapatite Thin Films on Titanium Substrates Prepared by Ultrasonic Spray Pyrolysis
(Materials Transactions, 2005)
Calciumhydroxyapatite thin films have been prepared by ultrasonic spray pyrolysis deposition on titanium substrate. The surface morphologies of the films formed at different deposition times were analysed by using SEM. The ...
