Nanoparticle

A nanoparticle is an incredibly tiny particle of matter that measures between 1 and 100 nanometers in size—so small that billions could fit on the head of a pin. Because of their minuscule size, nanoparticles behave differently from larger materials and can move through the body or environment more easily, making them useful for applications like medicine, electronics, and cosmetics. Scientists are researching nanoparticles to develop new treatments for diseases, create stronger and lighter materials, and improve products we use every day.
