This study aims to exploiting acoustic cavitation (US) to develop an oxytetracycline based antibacterial nanocomposites coupled with Au or Ag metal nanoparticle (NP) using pectin as carrier. UV-Vis spectroscopy and FESEM revealed that US strongly improved the metal NP dispersion. The US synthesized materials exhibited significant antimicrobial activity against gram (+) and gram (−), as evidenced by zone of inhibition tests.

超声驱动的金和银纳米粒子在柑橘果胶上的沉积：抗菌复合材料的制备和表征

本研究旨在利用声空化（US）开发一种以土霉素为基础的抗菌纳米复合材料，并以果胶为载体与金或银金属纳米颗粒（NP）偶联。紫外-可见光谱和场发射扫描电子显微镜表明，US 极大地改善了金属纳米粒子的分散性。美国合成材料对革兰氏菌 (+) 和革兰氏 (−) 表现出显着的抗菌活性，如抑制区测试所证明的那样。
