ZnAl layered double hydroxides impregnated with eucalyptus oil as efficient hybrid materials against multi-resistant bacteria

摘要

Bacterial contamination poses a serious hazard for human health. The use of bactericidal materials, such as layered double hydroxides, might constitute a way to reduce the risk of diseases. In this work, ZnAl layered double hydroxides were synthesized by microwave irradiation at different pH values and various metal molar ratios to be tested against multi-resistant bacteria. The synthesis conditions were chosen to form, in some cases, a composite containing zincite (ZnO), as both materials, zincite as well as the layered double hydroxide, are well known to be efficient antimicrobials.
