Origanum vulgare mediated green synthesis of biocompatible gold nanoparticles simultaneously possessing plasmonic antioxidant and antimicrobial properties

摘要

PurposeThe leaves and flowering stem of Origanum vulgare contain essential oils, flavonoids, phenolic acids and anthocyanins. We propose a new, simple, one-pot, O. vulgare extract (OVE) mediated green synthesis method of biocompatible gold nanoparticles (AuNPs) possessing improved antioxidant, antimicrobial and plasmonic properties.
