Nanomaterials
Nanomaterials are materials that have a size range of nanometers, typically between 1 and 100 nanometers. At this scale, materials have unique physical, chemical, and biological properties that differ from their bulk counterparts.
Nanomaterials have unique properties such as a high surface area to volume ratio, increased reactivity, and unique electronic and optical properties. These properties make them useful for a wide range of applications, such as drug delivery in medicine, catalysis in chemistry, and energy conversion and storage in energy science.
However, their potential health and environmental risks are also a topic of concern and ongoing research.
