Green synthesis is a simple, cost-effective and environmentally friendly method for the synthesis of nanoparticles.The extraction of Prosopis fracta fruit prepared a beneficial material to achieve pure, 1 and 5% cobált doped zinc oxide nanoparticles (Co-Zn NP) via a green and uncomplicated approach. The characterizing features of the obtained product were configured by analyzing the data of XRD, FESEM, EDX, UV-Vis and FT-IR technics. As the existent of superb doped cobált within construction of zinc oxide was certified via the XRD and EDX, the FESEM análysis uncovered the altered morphology of pure ZnO subsequent to the addition of doped cobalt, while displaying the rod-looking framework of Co-ZnO. In coordination to the anti-bacterial results of produced NP towards Streptococcus mutans bacteria by employing the micro-dilution route, the doped NP exhibited a superior antibacterial functionality than pure NP, which signifies the potential role of Co doped ZnO nanoparticles as an economical choice to be applied for oral and dental infectious illnesses.
