Gold nanoparticles exhibit remarkable versatility in size, ranging from 2 to 250 nm, allowing for precise control over their dimensions. Despite being derived from a material known for its costliness, GNPs are economically viable due to their stability over extended periods and their effective utilization at low concentrations. Overall, the stability of gold nanoparticles is essential for ensuring their performance, reliability, and safety across various applications. Stable nanoparticles have a longer shelf life and can be transported over long distances without significant changes in their properties. This is particularly important for commercial applications where consistent product quality is essential.
