A novel drug delivery system based on carboxymethyl cellulose containing copper oxide at melamine and zinc oxide at melamine framework (CMC-Cu-MEL and CMC-Zn-MEL) was prepared by the hydrothermal route. Synthesized nanocomposites were characterized by FTIR, SEM, and Raman spectroscopy. In addition, transmission electron microscopy (TEM) and selected area electron diffraction (SAED) images were applied to confirm the particle size and diffraction pattern of the prepared nanocomposites. Furthermore, the crystallinity of the synthesized CMC, CMC-Cu-MEL, and CMC-Zn-MEL materials was studied via X-ray diffraction (XRD). Estimating the transport exponent, which discloses the solvent diffusion and chain relaxation processes, and the Ritger-Peppas kinetic model theory were used to control the TC release mechanism from CMC-Cu-MEL and CMC-Zn-MEL. Additionally, the CMC-Cu-MEL and CMC-Zn-MEL containing TC had the highest activity index percents of 99 and 106% against S. aureus and 93 and 99% against , respectively. The tailored CMC-Cu-MEL and CMC-Zn-MEL for drug delivery systems are expected to be feasible and efficient.
通过水热法制备了一种基于含有三聚氰胺负载氧化铜和三聚氰胺骨架负载氧化锌的羧甲基纤维素的新型药物递送系统(CMC-Cu-MEL和CMC-Zn-MEL)。通过傅里叶变换红外光谱(FTIR)、扫描电子显微镜(SEM)和拉曼光谱对合成的纳米复合材料进行了表征。此外,应用透射电子显微镜(TEM)和选区电子衍射(SAED)图像来确认所制备纳米复合材料的粒径和衍射图案。此外,通过X射线衍射(XRD)研究了合成的CMC、CMC-Cu-MEL和CMC-Zn-MEL材料的结晶度。利用估算揭示溶剂扩散和链松弛过程的传输指数以及Ritger-Peppas动力学模型理论来控制CMC-Cu-MEL和CMC-Zn-MEL中替考拉宁(TC)的释放机制。此外,含TC的CMC-Cu-MEL和CMC-Zn-MEL对金黄色葡萄球菌的活性指数百分比最高,分别为99%和106%,对[此处原文缺失一种菌名]的活性指数百分比分别为93%和99%。用于药物递送系统的定制CMC-Cu-MEL和CMC-Zn-MEL有望是可行且高效的。
