The electrolysis method for synthesizing hydroxyapatite nanoparticles (NPs) has the advantage of controlling particle size by adjusting potential and current used. This study aims to NPs formation its characteristics. solution contained Na2H2EDTA.2H2O, KH2PO4, CaCl2, with an EDTA/PO43-/Ca2+ concentration 0.2/0.2/0.2 M. electrolytic are 4, 5, 6 volts hours. carbon electrode spacing used is 2 cm....
Europium doped hydroxyapatite (EDA) nanorods with linoleic acid passivated silver ions on their surfaces were synthesized using facile, one-step hydrothermal route. Annealing the samples at 250 °C resulted in formation of ultra-small silver (USS) nanoparticles on the surface by nucleation through diffusion process. EDA exhibited luminescence properties due to the presence of europium ions doped...

In this work, Fourier Transform Infrared spectroscopy (FT-IR) analysis were conducted on europium doped hydroxyapatite, Ca10-xEux(PO4)6(OH)2 nanocrystalline powders (Eu:HAp) with 0 ≤ xEu ≤ 0.2. Antimicrobial studies were also performed for the first time on Eu:Hap. The antimicrobial properties of Eu:HAp nanoparticles with 0 ≤ xEu ≤ 0.2 on Gram-negative (E coli ATCC 25922, Pseudomonas aeruginosa...
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...
Encapsulation of DNA into hydroxyapatite (HAp) has been investigated using a rational approach that involves computer simulation and experimental techniques. The temporal evolution of the radial distribution functions derived from atomistic molecular dynamics simulations of Ca(2+), PO4(3-) and OH(-)-containing aqueous solutions in the presence and absence of B-DNA has been used to conclude that...
Hydroxyapatite (HA) has been widely used as a biocompatible ceramic in many areas of medicine, but mainly for contact with bone tissue, due to its resemblance to mineral bone. In mammals, the skeleton presents a carbonated and partially substituted apatite, based on nanocrystal aggregates, and associated with collagen, building up 3-D structures present in various bone tissue conformations like...
