Sentences with phrase «magnetic nanoparticles»

"Magnetic nanoparticles" refers to very tiny particles that have special magnetic properties. These particles are so small that we cannot see them with our eyes, but they can be used in a variety of applications such as medicine, electronics, and environmental clean-up. They can be manipulated using magnets and are capable of attracting and capturing other substances, which makes them useful in various fields. Full definition
