Abstract

Fourier transform infrared spectroscopy (FT-IR) analysis was conducted on europium-doped hydroxyapatite,Ca10-xEux(PO4)6(OH)2nanocrystalline powders (Eu:HAp) with0≤xEu≤0.2. Antimicrobial studies were also performed for the first time on Eu:HAp. The antimicrobial properties of Eu:HAp nanoparticles with0≤xEu≤0.2on 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.
