SYNTHESIS AND ANTIBACTERIAL STUDY OF NICKEL OXIDE NANO PARTICLE USING AQUEOUS EXTRACTS OF CARICA PAPPAYA LEAVES

Nanoparticles are important role drug delivery systems in the medical fields. The present study was synthesis of nickel oxide nanoparticles using aqueous extracts of Carica papaya leaves. The nanoparticles was characterized by X ray diffraction method and its pharmacological studies was carried out against the bacterial strains of Strephylococcus aureus, Strephylococcus epidermidis, Proteus mirabilis and Klebsiella pneumoniae. The zone of inhibition in the petriplates and the graphical representations indicates that antibacterial activity has been dose dependant mode because increase the concentration the activity also increases.
