While it's true that nanoscience is the study of materials at the nanoscale, it's more focused on understanding the properties of materials at that level. Nanotechnology, on the other hand, focuses on the design, production, and application of those materials.
Think of it this way:
* Nanoscience: Understanding how things work at the nanoscale.
* Nanotechnology: Building and using things at the nanoscale.
Therefore, nanotechnology encompasses the broader field, including the study of molecules and structures within that size range.
