Zinc oxide nanoparticles (Zinc Oxide Nanopowder) or ZnO Nanoparticles are minute particles of zinc oxide having diameters of fewer than 100 nanometers. They feature a vast surface area for their size and high catalytic activity. Zinc is an essential inorganic element widely utilized in health, biology, and industry. An adult’s daily consumption is 8–15 mg/day, with around 5–6 mg/day lost through urine and perspiration. It is also a necessary component of bones, teeth, enzymes, and many functioning proteins. Zinc metal is required for the growth of humans, animals, plants, and microbes, but Zinc Oxide Nanopowder is poisonous to many fungi, viruses, and bacteria. Acrodermatitis enteropathica, a hereditary illness characterized by python-like rough and scaly skin, affects people who have an intrinsic genetic deficit of soluble zinc-binding protein.
ZnO is a wide-bandgap semiconductor with a room-temperature energy gap of 3.37 eV. ZnO, titanium dioxide, and silicon dioxide nanoparticles are the three most created nanomaterials. The precise physical and chemical characteristics of zinc oxide nanoparticles are determined by the many methods by which they are produced. Sunscreen is the most frequent applications of nanoparticles. They utilize it because they absorb UV light effectively while having a broad enough bandgap to be entirely transparent to visible light. They are also being researched for their ability to destroy dangerous bacteria in packaging and UV-protective materials such as textiles. Many firms do not identify nanoparticle-containing items, making it impossible to establish claims regarding their manufacturing and pervasiveness in consumer products.
ZnO nanoparticles can be utilized as Nano-optical and Nano-electrical devices in the industry, as antibacterial and antitumor agents in food packaging, and as antimicrobial and antitumor agents in medicine. High luminous efficiency combined with a significant exciton binding energy (60meV) has sparked considerable study into the manufacture of nanoparticles utilizing various synthetic techniques and their potential uses. Due to their small size, Nanoparticles can typically move throughout the body and have been proven in animal experiments to permeate the placenta, blood-brain barrier, individual cells, and their nuclei. Because nanoparticles are a novel material, there is worry about the possible risks they may pose. Laser ablation, hydrothermal techniques, electrochemical depositions, sol-gel method, chemical vapor deposition, thermal decomposition, electrophoretic deposition, and precipitation processes employing solution concentration, pH, and washing media are some methods for producing ZnO nanoparticles.
It is less hazardous than silver nanoparticles at a wide concentration range. The spectrum of an aqueous solution of Zinc Oxide Nanopowder shows peaks between 370 and 385 nm. In the presence of moisture, it creates ROS (hydroxyl radicals, superoxide, and hydrogen peroxide), which ostensibly react with bacterial cell components such as protein, lipids, and DNA, finally inducing death.
Applications of Zinc Oxide Nanoparticles
Zinc oxide is a necessary component of several enzymes, sunscreens, and anti-itch ointments. Because of their broad band gap, its microcrystals are extremely effective light absorbers in the UVA and UVB regions of the spectrum. They are more potent against microorganisms such Sarcina lutea, Bacillus subtilis, Bacillus megaterium, Klebsiella pneumonia, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Pseudomonas Vulgaris, Candida albicans, and Aspergillus Niger. The effect of zinc oxide on biological activities is determined by its shape, particle size, exposure period, concentration, pH, and biocompatibility.
Zinc oxide nanoparticles are renowned for their low toxicity, making them an excellent option for application in the biomedical area. The strong and stiff structure of Zinc Oxide Nanopowder makes them valuable in the ceramic industry. It is naturally known to have high microbial resistance, widely used for biological sensing, drug delivery, biological labelling, gene delivery, and nano-medicine. Zinc oxide has been certified as a safe material by the Food and Drug Administration.
