In the present investigation, the ZnO Ã¢â‚¬ÂAu nanocomposites were prepared bydissolving the Zinc Nitrate and Chloroauric acid in 1:1 concentration in thepresence of Sodium Hydroxide. Formation of nanocomposites was observedby a change in color from a colorless solution to yellowish white precipitate.Furthermore, characterization of ZnO Ã¢â‚¬ÂAu nanocomposities were done byusing Atomic Force Microscope (AFM), UV absorption Spectroscopy, ScanningElectron Microscopy (SEM) and X Ã¢â‚¬Âray Diffraction (XRD) to determine theparticle size, absorption, morphological studies and crystalline structure.Moreover, under the evaluation of anti Ã¢â‚¬Âmicrobial potential of synthesizedcomposites, a great promise as anti Ã¢â‚¬Âbacterial agent was observed which canfind versatile applications in the fields such as medical devices and antimicrobialsystems.

Most of the people in rural and urban areas of the world were dependent onthe medicinal plants for the treatment of infectious diseases. The Ayurvedicand Unani systems of medicines are widely used by the people of Indian subcontinent.Among the different plant derivatives, secondary metabolitesproved to be the most important group of compounds that showed widerange of antibacterial and antifungal activity. Eupatorium triplinerve(Compositae) is a slender herb with narrow lanceolate leaves and large numberof pedicelled flower Ã¢â‚¬Âheads at the top of the branch. Extract of the plantis used as antiseptic, and in the treatment of various ulcers and haemorrhages. This paper reviews the antimicrobial potential of leaf extracts of eupatorium triplinerve.
