Final answer:
A sock manufacturer would use silver nanoparticles instead of ordinary silver particles because nanoparticles have unique properties that make them more effective in preventing bad smells. These properties include a high surface area-to-volume ratio, smaller size for better penetration of fabric, and controlled release of silver ions for long-lasting effects.
Step-by-step explanation:
A sock manufacturer would use silver nanoparticles instead of ordinary silver particles because nanoparticles have unique properties that make them more effective in preventing bad smells. One of these properties is the high surface area-to-volume ratio of nanoparticles, which allows for more contact with the odor-causing molecules in the sock. This increased contact enhances the antimicrobial properties of silver, preventing the growth of odor-causing bacteria. Additionally, nanoparticles have a smaller size, allowing them to penetrate the fabric of the sock more easily and distribute evenly.
Furthermore, the use of nanoparticles allows for a controlled release of silver ions, which are responsible for the antimicrobial activity. The smaller size of nanoparticles increases the rate at which silver ions are released, providing a continuous and long-lasting effect. On the other hand, ordinary silver particles have a larger size, which results in slower and less efficient release of silver ions.
Overall, by using silver nanoparticles, the sock manufacturer can achieve better and more reliable antimicrobial properties, leading to the prevention of bad smells and improved comfort for the wearer.
