silica nanoparticles

Silica nanoparticles are tiny particles made from silica, the same material found in quartz and sand, but on a much smaller scale—typically less than 100 nanometers in size. Their small size gives them unique properties, such as a large surface area and high reactivity, making them useful in various applications like medicine, electronics, and coatings. Due to their size, they can penetrate biological systems or surfaces more easily and can enhance strength, durability, or functionality in products. Despite their smallness, silica nanoparticles are generally considered safe when used properly, though their safety depends on the specific use and form.
