GlossaryNanocrystals

tiny particles a few nanometers in size with unique properties

Nanocrystals are tiny particles that are only a few nanometers in size, often composed of a single crystal structure. They exhibit unique physical and chemical properties due to their small size and high surface area, making them useful in various applications such as drug delivery, electronics, and cosmetics. For instance, in hair care, nanocrystals can enhance the delivery and effectiveness of active ingredients in treatments for conditions like alopecia.
