Nowadays, development of new antimicrobial agents to replace antibiotics, especially biological compounds, is of great interest. In this study, the synthesis of nanoliposomes loaded with clove essential oil and their use as an antibacterial and antifungal agent in MHA and PDA media,respectively were investigated. For this purpose, liposomes were synthesized by the ethanol injection method using lecithin as a precursor in the presence of clove essential oil, and their physicochemical properties were investigated by transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), dynamic light scattering (DLS) and zetasizer. Then, their antimicrobial effects were investigated on Escherichia coli and Staphylococcus aureus bacteria, and Aspergillus niger, Aspergillus terreus and Aspergillus flavus fungi. Nanoliposomes loaded with clove essential oil showed high colloidal stability with a zeta potential of -58.5 and no sedimentation was observed even after 6 months. TEM imaging showed that the nanoparticles had a hemispherical and homogeneous shape with a size range of 100-200 nm. Nanoliposomes showed high biocompatibility as 73.8 and 81.3% of human fibroblast cells remained viable after incubation with 200 μg mL-1 of the initial and clove essential oil-loaded nanoliposomes, respectively. Although nanoliposomes loaded with clove essential oil showed limited antibacterial effect against Staphylococcus aureus and Escherichia coli strains, they showed a potent antifungal effect on A. niger, A. terreus and A. flavus, with the complete growth inhibition of fungal mycelia at concentrations of 2, 2, and 1 mg mL-1 (m/v), respectively. Based on the results, clove essential oil-loaded nanoliposomes can be a suitable antifungal agent for food and pharmaceutical applications.
