摘要
研究了菌根菌(正克)和大肠杆菌(负克)的抗菌活性能力，使用高浓度Ag的纳米复合材料/TiO2、nata de coco/Ag和nata de coco/Ag的高浓度变化;0.6米;70米;使用化学还原方法0.8米(2英尺)和0.9米(2英尺)。这些纳米粒子的特点是x射线衍射、扫描电子微scoy -energy x射线显微扫描和抗菌。用圆盘纸方法测试抗菌活性，每个样本和测试细菌进行两次复查。研究表明，抑制细菌生长的最有效的纳米复合材料是纳米合成物——可可/TiO2/Ag——能够抑制Escherichiacoli和葡萄球菌菌的生长，但这些复合材料更有效地抑制了Escherichiacoli细菌和葡萄球菌的生长。用nata de coco /纳米合成TiO2、nata de coco / Ag、0。6米(20英尺);0。7米;使用化学还原方法0.8米和0.9米。纳米颗粒被x射线衍射、扫描电子微镜显微扫描x射线spctroscopy (semc - eds)和反细菌事件制度化。使用纸质传播工具和重复两个样本，测试抗菌活性。再生结果表明，在抑制细菌生长中纳米可裂变的活性是纳米可释放的大肠杆菌和大肠杆菌的生长，但纳米复合更有效地抑制了大肠杆菌的生长。
