Since few decades, the fabrications of metal oxide nanoparticles (MO-Nps) as well as their uses in various segments have been increased manifolds. An easy effort to produce an important category of MO-Nps as Zinc oxide nanoparticles (ZnO-Nps), with the assistance of mechano-solution method at various low temperatures, introducing Zinc acetate dihydrate and Sodium hydroxide into the molar solution of C19H42NBr complex (Cetrimonium bromide, CTAB) for much less than an hour was projected. The impact of this method performed at two different ranges of process temperatures was studied and the magnitude of the ZnO-Nps (like particle size, morphology and L/D dimensions) has been reported. On the top of this, the morphological study of these Nps has been presented. The characterization of the synthesized Nps was carried out with the help of SEM with EDS, XRD, UV-Vis spectroscopy. The scanning electron microscopy has revealed the synthesis of peanut-shaped ZnO nanobunches (NBs) at two different ranges of temperature. An overall viable growth of the solitary nanoparticles constituting of ZnO-NBs has also been put forth. Hence, the effect of temperature on C19H42NBr complex (stabilizer) has been reported. In addition, a postulated model depicting the relationship of the temperature effect on the process parameters of ZnO-NBs has also been floated. The Gram +ve bacteria, Bacillus subtilis is a rod shaped bacteria which is commonly known as normal gut commensal in humans. Due to the emergence of anti-biotic resistant drugs, alternate medications are under primary considerations. A noteworthy experimentation was concerned with anti-bacterial activity of therapeutically viable Gram +ve bacteria, Bacillus subtilis and it was found that reported ZnO-NBs have become the promising entities for terminating the growth of these bacterias.
