Just scratch your self-assembled monolayer with a razor knife!

But is it nano?

Hydrophilic

Hydrophobic

Page 5: Surfaces & Nanorods A quick survey of these heavy hitters: Whitesides Alivisatos And one promising young investigator: Velev

Patterning;

possibilities

include massively parallel detection, fly-eye

lens, etc. But is it nano?
