Colloidal Nanoparticles
Colloidal nanoparticles are tiny particles, measured in nanometers (billionths of a meter), suspended evenly throughout a fluid, like liquid or gas. Due to their small size, they have unique properties—such as increased surface area and reactivity—that differ from bulk materials. These nanoparticles are used in various applications, including medicine (drug delivery), electronics, sunscreens, and catalysts, enhancing performance and enabling innovative solutions. Their stability in suspension depends on factors like surface charge and the surrounding medium, making their control crucial for effective use.
