What is Nanoscience?
Nanoscience is the study of structures and materials on the scale of nanometers, typically ranging from 1 to 100 nanometers. It focuses on understanding the unique properties that emerge at this extremely small scale. These properties often differ significantly from those seen in bulk materials, making nanoscience a vital area of research within the broader field of
Nanotechnology.
Why is Nanoscience Important?
Nanoscience is critical because it enables scientists to manipulate materials at the atomic and molecular level. This manipulation leads to unique mechanical, electrical, optical, and chemical properties. These unique properties have vast implications for various industries such as
medicine,
electronics,
energy, and
materials science. For instance, in medicine,
nanoparticles can be used for targeted drug delivery, potentially reducing side effects.
