Zinc Oxide Powder Nanoparticles: Fundamental Properties and Applications

Zinc Oxide Powder

Zinc Oxide is the fifth most common element found inside the crust of the earth. Unlike other metal oxide nanoparticles, zinc oxide is less toxic and cost-effective. Besides, it possesses exceptional bio-compatibility to that of Ti02 (titanium dioxide). Its diameter is less than one hundred nanometers. 

Nanoparticles of zinc oxide are an ideal candidate for various applications of research in biomedicine. This is particularly due to the antifungal, antibacterial, and anticancer properties.  Nanoparticles of zinc oxide have the potential to generate reactive oxygen species and can trigger apoptosis. Zinc oxide powders are not self-inflammable. 

Another major highlight regarding zinc oxide nanoparticles is that their features and properties are based on the production technique. This blog focuses on these properties and their applications.

Properties of zinc oxide

Zinc oxide is a compound that develops either as a whitish dusty powder or colorless hexagon-shaped crystals. Owing to its distinctive properties, zinc oxide powder is an ideal choice for diverse range of applications.

When zinc oxide is allowed to heat, it gets converted into lemon yellow and reverts to white color once it is cooled. It sublimates without even melting at extreme temperatures. The estimated density is about 5.61 cm cube. Zinc oxide evaporates at 1300 degrees centigrade.

Even at room temperature, ZnO is a wide-band gap semiconductor that is capable of producing reactive oxygen species to exterminate cells. Thus making it very useful in bio-sensing.

Nanoparticles of ZnO can be transfigured in a different manner. They possess excellent antibacterial activity against gram-positive bacteria. ZnO should be nontoxic, and non-reactive for human consumption.

Applications of Zinc oxide powders

Being a versatile inorganic compound, it is used in a variety of fields. Some of them are as follows

Sunscreen

ZnO nanoparticles are frequently utilized in sunscreen for UV protection.

Anti-cancer

Zinc oxides are promising inorganic compounds, especially in curing cancer owing to their selective toxicity.

Antidiabetic activity

ZnO plays a crucial role in the storage of insulin, synthesis, and secretion. They are also capable of reversing diabetes-induced pancreatic injury.

Conclusion

Zinc oxide nanoparticles are less than one hundred nanometers in terms of diameter and possess a massive surface area. This is very helpful to boost their catalytic activity. Its properties are based on the synthesis techniques, which makes it an ideal option for biomedicine. These excellent properties make ZnO nano particles reliable antifungal and antibacterial agents.
