Zinc Oxide nanoparticles have been synthesized by two simple routes using Aloe vera (green synthesis, route I) or Cassava starch (gelatinization, route II). The XRD patterns and Raman spectra show that both synthesis routes lead to single-phase ZnO. XPS results indicate the presence of zinc atoms with oxidation state Zn2+. SEM images of the ZnO nanoparticles synthesized using Cassava starchThe synergistic potential of silver and zinc oxide nanoparticles for water disinfection was investigated herein. By causing cell death through membrane interactions, oxidative killing, and DNA deactivation, metallic nanoparticles may be integrated with point-of-use water treatment systems for applications in rural and remote geographies.
Abstract Metal oxide nanomaterials are one of the preferences as antibacterial active materials. Due to its distinctive electronic configuration and suitable properties, ZnO is one of the novel antibacterial active materials. Nowadays, researchers are making a serious effort to improve the antibacterial activities of ZnO by forming a composite with the same/different bandgap semiconductor
Nano comes from the Greek word “nanos,” which means “dwarf”—and nanoparticles are, therefore, extremely small. Specifically, nanoparticles are those smaller than 100 nanometers, while non-nano particles are 100 nanometers or larger. The nanoparticles used in many mineral sunscreens are as small as 10-20 nanometers, which means they To solve the problem of liquid-phase synthesis of nano-ZnO, a photocatalytic performance study was proposed. In this study, the microwave homogeneous precipitation method was used to add different types and amounts of surfactants. The synthesis of nano-zinc oxide was controlled by changing the reaction system conditions. Non-Nano Zinc Oxide: Badger Balm Sunscreens One of my favourite non-nano zinc oxide (non-nano meaning: does not soak into your blood stream) sunscreens is made by Badger Balm . If you follow me on Instagram , you have probably seen a few posts with Badger Balm sunscreens. The purpose of this study was to evaluate the effect of nano‐zinc oxide (ZnO‐N) morphology on the functional and antimicrobial properties of tapioca starch films. For this reason, nanosphere (ZnO‐ns), nanorod (ZnO‐nr), and nanoparticle of ZnO (ZnO‐np) at 0.5%, 1.0%, and 2.0% were added to the starch film.Looking for a zinc sunscreen that doesn't leave a whitecast? What about non-nano sunscreens - can you have both and still get a sheer finish?
