A nanocrystal is a tiny particle made of a solid material, typically measuring between 1 and 100 nanometers in size. These particles have unique properties due to their small size and high surface area, which can differ significantly from their bulk counterparts. Nanocrystals are often used in various applications, including electronics, medicine, and energy storage. The synthesis of nanocrystals can involve methods like chemical vapor deposition or sol-gel processes. Their unique characteristics make them valuable in fields such as nanotechnology, where they can enhance the performance of solar cells and improve the effectiveness of drug delivery systems.
