The present study reports about green method for the synthesis of gold nanoparticles using plant essential oil menthapiperita. The effects of gold concentration, extract concentration and extract quantity were identified through nanoparticles synthesis. Gold nanoparticles of synthesized essential oil menthapiperita were characterized with different techniques such as UV–Vis spectroscopy, SEM-EDX, X-ray diffraction, transmission electron microscopy and fourier transform infrared spectroscopy. Transmission electron microscopy showed that these nanoparticles are 60 nm. The SEM image showed that theses gold nanoparticles are small dot round shaped structure. X-ray diffraction pattern showed these gold nanoparticles are powdery in nature. Clinical isolates in the group of molds such as Aspergillusniger, Aspergillusflavus, and yeast like fungi such as Candida tropicalis, Candida albicans and Candida kefyr, were used for antifungal assay. The synthesised gold nanoparticle essential oil menthapiperita showed high activity against these deadly pathogenic fungi.
