Nanoparticles

sunscreen: zinc oxide and titanium dioxide nanoparticles in sunscreens absorb UV light without reflecting visible light because they are smaller than the wavelength of visible light, making the sunscreen transparent

self cleaning surfaces: coatings with titanium dioxide nanoparticles on window glass can break down organic material and prevent water droplets from forming, thus cleaning the glass

polymer coatings containing nanoparticles like carbon nanotubes create nano-sized structures that repel water and dirt, mimicking the lotus effect
