ZnO and Cynodon Dactylon capped concentrations on ZnO (Cy-da/ZnO) nanoparticles have been synthesized. XRD data and SEM analysis showed that the crystallite size of NPs with hexagonal nano-rod structure. The blue shift behavior observed by UV-Vis and the estimated value of band gap were observed to be 3.3, 3.45 and 3.5 eV for ZnO, (5ml) Cy-da/ZnO and (10ml) Cy-da /ZnO NPs respectively. ROS and ML-DNA were tested and estimated for Cy-da doped ZnO NPs by Klebsiella pneumoniae. The highest antibacterial activity against Gram negative bacteria’s for (10ml) Cy-da/ ZnO NPs when compared to ZnO NPs and (5ml) Cy-da /ZnO NPs.

已经合成了ZnO和Cynodon Dactylon在ZnO（Cy-da / ZnO）纳米粒子上的上限浓度。XRD数据和SEM分析表明，具有六方纳米棒结构的纳米颗粒的晶粒尺寸。对于ZnO，（5ml）Cy-da / ZnO和（10ml）Cy-da / ZnO NPs，通过UV-Vis观察到的蓝移行为和带隙估计值分别为3.3、3.45和3.5 eV。肺炎克雷伯菌检测并估算了ROS和ML-DNA的Cy-da掺杂ZnO NPs 。与ZnO NP和（5ml）Cy-da / ZnO NP相比，对（10ml）Cy-da / ZnO NPs对革兰氏阴性菌具有最高的抗菌活性。
