Introduction
Nanoscience and nanotechnology are intertwined fields that delve into the manipulation and study of matter at the nanoscale (1-100 nanometers). This scale is incredibly small, roughly 100,000 times thinner than a human hair. At these dimensions, materials often exhibit unique properties not seen at larger scales, opening a world of possibilities in various industries.
