Abstract:
Objective:To study the antimicrobial properties of CaO/ZnO core-shell nanoparticles.Methods:The CaO/ZnO core-shell nanoparticles were prepared via precipitation method.The pH and calcium ion release from the samples which composed of eugenol and nanoparticles were examined respectively.The form of the particles was observed under electron microscope,the ions were analysed by inductively coupled plasma(ICP).The antibacterial activities against Streptococcus mutans,Enterococcus faecalis,Escherichia coli and Staphylococcus aureus were evaluated by agar diffusion test (ADT).Results:CaO/ZnO core-shell nanoparticles were spherical with core-shell structure and with the diameter of 80-90 nm.The calcium ion release and pH were gradually increasing from the nanoparticles in PBS.The antibacterial activity of CaO/ZnO core-shell nanoparticles-eugenol was significantly greater than that of iRoot SP and zinc oxide-eugenol sealer(P<0.01).Conclusion:CaO/ZnO core-shell nanoparticles possess antibacterial activity.
