In the context of nanotechnology, strong adhesion refers to the ability of materials to adhere to each other at the nanoscale level with exceptional strength. This property is critical for many applications, such as nanoelectronics, nanomedicine, and nanocomposites. At this scale, the interactions between materials are governed by forces like van der Waals forces, hydrogen bonding, and sometimes covalent bonding, which can be significantly stronger than those observed at the macroscale.
