DID YOU KNOW

– Nanoparticles are incredibly small, measuring between 1 and 100 nanometers in size. To put this into perspective, a sheet of paper is about 100,000 nanometers thick. Due to their small size, nanoparticles exhibit unique properties and behaviors that differ from their bulk counterparts. This makes them highly valuable in various fields, such as medicine, electronics, and environmental science.

– Gold nanoparticles have been used for centuries in stained glass windows to create vibrant colors. The size and shape of the nanoparticles determine the color they produce. For example, smaller gold nanoparticles appear red, while larger ones appear blue. This phenomenon is known as the “plasmonic effect” and is now being harnessed for applications in imaging, sensing, and even cancer treatment.

– Nanoparticles can be found in unexpected places, such as your sunscreen. Many sunscreens contain zinc oxide or titanium dioxide nanoparticles, which help to block harmful UV rays. These nanoparticles are transparent and provide effective protection without leaving a white residue on the skin. However, their safety and potential environmental impact are still subjects of ongoing research and debate.
