Nanoparticles
Nanoparticles are extremely tiny pieces of a substance. Even though they may be tiny, they actually have far more effects to their surrounding than the normal substance. While a chunk of silver is a great bacteria cleaner and used in most infection medicines, a pinch of nanosilver is a ruthless bacteria killer that is used in urgent hospital infections and can clear up all bacteria from an injury in a few seconds. You are most likely confused now, as it doesn’t exactly make sense that a powder of a substance is better than a chunk of it. The reason has to do with the very large surface area. If you have a 2 cm x 2 cm cube, it will have 24cm ² of surface area. If you divide that cube into 8 - 1 cm x 1 cm cubes, it will h ave 48cm² of surface area. Following this logic, 1kg of silver powder would have much more surface area than a chunk of silver weighing 1kg. The surface area increase is critical, as when you have a large chunk, the center won’t get used. However, extremely tin...
