Nanoscale science from the mechanisms up — surface area, quantum confinement, characterisation — and an honest account of what it takes to manufacture any of it.
The foundational topics in nanotechnology.
Nanotechnology is defined by scale rather than substance. Here is what changes between 1 and 100 nanometres, why it changes, and why a nanoparticle of a familiar material can be a genuinely new one.
Why a drug-delivery nanoparticle has a core, a shell, a polymer coat and a targeting ligand — told as the sequence of failures each layer was added to solve.
Discovery, characterisation, pilot line, product. What each stage measures, what kills projects at each one, and why most of the field is permanently in the first two.

The human-hair comparison tells you nothing useful. Six anchors at the right order of magnitude, and the two mechanisms that make small materials behave differently.
Why a quantum dot's colour is set by its size, and why the journey from a 1981 observation to a shipping display took three decades of manufacturing rather than physics.
