nanostructured lipid carriers loaded with melaleuca alternifolia oil preparation, physicochemical assessment, and evaluation of antimicrobial effects against staphylococcus epidermidis

Thanks to their outstanding advantages, nanostructured lipid carriers (nlcs) have recognized in various fields these days. one way to discover extra useful products against typical bacteria (e.g., staphylococcus epidermidis) is nlcs loaded with essential oils. this paper aims to provide nlcs to encapsulate ma oil, characterize, and survey the obtained ma oil-loaded nlcs on s. epidermidis. the combination has provided using the hot melt homogenization technique. afterward, the particle size distribution (psd) (particle size analyzer), morphology (sem), zeta potential (surface charge of nlcs), and the stability (the effect of acidity) of the prepared nlcs were analyzed. this has followed by estimating the mic of ma oil-loaded nlcs and comparing carriers and oil emulsion of ma against s. epidermidis. ma oil-loaded nlcs are spherical nps with a mean size of 104.5 nm and narrow size distribution (pdi=0.22). the antibacterial evaluation results demonstrated that ma oil-loaded nlcs had a higher in vitro antimicrobial activity compared to the oil emulsion of ma. consequently, nlcs could be a suitable carrier to enhance new antimicrobial agents.
