Phytogenic synthesis of Cr2O3 nanoparticles using plant extract

Abstract

Currently, chromic oxide nanoparticles are one of the noteworthy nanoparticles with exceptional applications in numerous fields of recent science. When Cr₂O₃ NPs is synthesized using plant extracts, it has several features like antidiabetic, anticancer, antiviral, antifungal, antioxidant, antibacterial and antileshmanial activity. Almost all parts of a plant such as flowers, leaves, fruits, roots contain terpenoids, alkaloids, tannins, flavonoids and phenols which can act as both reducing and stabilizing agent. In recent times, plant extracts like Opuntia Ficus indica [1], Ipomoea batatas [2], Nephelium lappaceum [3], Melia azedarach [4], Artemisia herba-alba [4], Mukia maderaspatana [5], Cannabis sativa [6], Tridax procumbens [7], Hyphaene thebaica [8], Callostemon viminalis [9] and  Rhamnus virgata [10] were reported for the synthesis of Cr₂O₃ NPs. SPR obtained in the range of 250–450 nm for the nanoparticles confirmed the synthesis of Cr₂O₃ NPs from its precursor. The average crystallite sizes of Cr₂O₃ NPs were in the range of 3 to 100nm which were calculated from XRD datas. The phytogenic synthesized Cr₂O₃ NPs exhibited excellent antileishmanial activity, antioxidant potential, anticancer activity, antiviral property, antifungal activity and antibacterial activity.
