Abstract

Abstract In this work, the biological and physical properties of colloidal platinum (PtNPs) and cobalt (CoNPs) nanoparticles were examined for antibacterial applications. The colladial PtNPs and CoNPs nanoparticles were produced using two different liquids (double-distilled water (DDDW) and Dulbecco’s Modified Eagle’s Medium (DMEM)) by laser ablation technique (PLAL). Characterization techniques such as transmission electron microscopy (TEM), UV-vis spectroscopy and Fourier transform infrared (FTIR) were used to determine some physical properties of PtNPs and CoNPs. The antibacterial effects ofcolladial PtNPs and CoNPs at different doses on various bacteria were investigated and their antibacterial activity resistances were calculated by measuring the inhibition zone widths. The effect of the liquid used in the production, the type of bacteria and dose amounts on the antibacterial resistance of these nanoparticles were determined. In this study, it has been shown that the liquid used in the production of PtNPs and CoNPs can create significant changes in the physical and antibacterial properties of nanoparticles, especially by changing the size and concentration of collodial PtNPs.
