Study on europium doped hydroxyapatite nanoparticles by Fourier transform infrared spectroscopy and their antimicrobial properties
نویسندگان
چکیده
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 1397) and Gram-positive (Staphylococcus aureus 0364, Enterococcus faecalis ATCC 29212) bacteria systems and a species of fungus (Candida albicans ATCC 10231) were reported. Our study demonstrates that the antimicrobial activity of Eu:HAp nanoparticles is dependent on the europium concentration.

In this paper, we report the structural and morphological properties of silver-doped hydroxyapatite (AgHAp) with a silver concentration x Ag = 0.5 before and after being thermal treated at 600 and 1000 °C. The results obtained by X-Ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and Raman spectroscopy suggest that the structure of the samples changes gradually, from hydro...
