Scientists, chemists, and business community were drawn attention towards the Zinc Oxide because of its advantageous physical, chemical, and biological properties. It has many desirable properties, including a large energy gap (3.37 eV) at room temperature, a higher excitation energy value (60 meV), a higher index of refraction, and good piezoelectric capabilities. On the other hand, zinc oxide and zinc oxide nanoparticles have demonstrated remarkable resistance to a variety of bacterial species.
Because of all these characteristics, ZnO’s turns into considered valuable substance of the future. As a result, this material can be used by scientists and engineers in everyday applications like solar cells, gas detectors, ultraviolet light-emitting diodes, diode-based lasers, and antimicrobial treatments.
Moreover, the incorporation of impurities into their crystal structure ZnO demonstrates that they are proficient in both positive and negative type of bacterial species. ZnO is mostly an N-type semi-metal in terms of its nature. The Zn and O2 defects in structure are responsible for the N-type behavior. However, the occupation of holes by existing electrons makes it difficult to generate stable p-type zinc oxide.
The aqueous chemical growth approach was used in this study to create lithium-incorporated zinc oxide nanoparticles. It investigates their optical, structural, and antimicrobial properties against Escherichia coli and Staphylococcus aureus bacteria. Nano-scale crystal rods created by aqueous chemical growth have been studied using a variety of methods, including photoluminescence, scanning electron microscopy, and X-ray diffraction. In this sense, the antibacterial properties have been observed over two distinct bacterial strains, Escherichia coli and Staphylococcus aureus, using the Broth Dilution Method.
Furthermore, a study using X-ray diffraction has confirmed that the produced nanoparticles are wurtzite and hexagonal. Similarly, all of the produced nanostructures are rod-like, one-dimensional, and have the same dimensional character, according to a study conducted using a scanning electron microscope. Ultimately, the photoluminescence study demonstrated the enhancement and alteration of zinc oxide's optical characteristics. The lithium-doped zinc oxide nanostructure demonstrated exceptional resistance to both Escherichia coli and Staphylococcus aureus germs in the antibacterial testing.
