Green Nanotechnology Techniques, Developing Eco-Friendly Methods for Creating Gold Nanoparticles and Examining their Antiviral Effectiveness against SARS-CoV-2

Environmentally-friendly methods are employed to produce gold nanoparticles (AuNPs), as well as to define their properties and apply them in the fight against cancer, including its early detection. Traditional cancer treatments like chemotherapy, radiation therapy, and surgery sometimes fail to affect certain cancer cells. Additionally, these treatments are known to have significant adverse effects and may not always be effective. This underlines the urgency for accelerated progress in research for anti-cancer therapies. Gold is highly favored in nanotechnology because it resists surface oxidation and is chemically inactive. Using green chemistry, nanoparticles are crafted from natural sources, prioritizing ecologically sound practices. Gold nanoparticles are an assembly of gold atoms forming particles that range from 1 to 100 nanometers, gaining remarkable physical, chemical, and optical properties through their minute dimensions and heightened surface area. Storing gold nanoparticles requires careful consideration to preserve their stability and prevent degradation. The antibacterial efficacy of these nanoparticles has been assessed using the agar well diffusion method. Moreover, by implementing the broth dilution technique, we can create biocompatible AuNPs with potential applications in biomedicine and other fields where non-toxicity is essential.
