Nanoparticle size

Nanoparticle size refers to how small these particles are, typically measuring between 1 and 100 nanometers (a nanometer is a billionth of a meter). To put it in perspective, a nanoparticle is hundreds of times smaller than the width of a human hair and about 100 times smaller than a virus. This extremely small size gives nanoparticles unique properties, such as increased reactivity and surface area, which can enhance their performance in various applications like medicine, electronics, and materials science. Understanding nanoparticle size is essential because it influences how they behave and interact with their environment.
