“…Recently, there has been significant progress in the development of new technologies related to antibacterial and antimicrobial coatings and composites due to the increasing concern regarding threats to public health (i.e., bacteria, fungi, and viruses). 1 Zinc oxide (ZnO) nanoparticles are considered good antimicrobial agents due to their safety, low toxicity, and biocompatibility towards humans, 2 in addition to their advantage of being low-cost materials. 3 The antibacterial mechanism of ZnO has been associated with the formation of reactive oxygen species (ROS), such as hydroxyl and superoxide radicals and H 2 O 2 , when nano-ZnO interacts with bacterial cells in the presence of moisture.…”

“…They can help avoid the contamination of food, water, and industrial equipment that may be contaminated by microorganisms. 1 Biodegradable and biocompatible polymers and their nanocomposites find applications in medicine, such as in tissue engineering, drug delivery, and biosensors. Other polymers, such as polyethylene, are not biodegradable, but they are harmless and have excellent mechanical properties.…”

Nanostructured zinc oxide (ZnO) prepared by combustion in solution was used to obtain nanocomposites. The ZnO particles were characterized by Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD), and scanning electron microscopy (SEM), showing crystallite size of 32 nm and a superficial area of 32.6 m 2 g -1 . Nanocomposites with 1, 3, and 5 wt.% of ZnO in the polymeric matrix were obtained using the in situ polymerization of ethylene with catalytic activities between 1500-1700 kg (mol Zr h P E ) -1 . The high-density polyethylene nanocomposites (PEZnO) were characterized by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), SEM, and transmission electron microscopy (TEM). The nanocomposites with 1 wt.% ZnO gave excellent mechanical properties, and all were active against Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria.
