具有持续药物释放性能的抗微生物材料的开发具有重要意义。 氧化石墨烯（GO）被认为是理想的药物载体。 在该研究中，将盐酸四环素（TC）加载到聚乙烯亚胺官能化的GO（PG）上以制备TC/PG纳米复合材料。通过zeta电位，TEM，FTIR和拉曼分析证实了制造的成功。TC/PG纳米复合材料显示出受控且持续的药物释放行为，并且采用伪二级动力学模型来说明释放机制。使用针对大肠杆菌和金黄色葡萄球菌的纸盘扩散法

具有持续药物释放性能的抗微生物材料的开发具有重要意义。 氧化石墨烯（GO）被认为是理想的药物载体。

在该研究中，将盐酸四环素（TC）加载到聚乙烯亚胺官能化的GO（PG）上以制备TC/PG纳米复合材料。通过zeta电位，TEM，FTIR和拉曼分析证实了制造的成功。TC/PG纳米复合材料显示出受控且持续的药物释放行为，并且采用伪二级动力学模型来说明释放机制。使用针对大肠杆菌和金黄色葡萄球菌的纸盘扩散法研究抗菌活性。结果显示，TC / PG纳米复合材料表现出很好的细菌抑制性能。

总之，该研究结果表明，制备的具有有效抗菌活性的TC/PG纳米复合材料在抗菌应用中具有很大的潜力。
