By confining and concentrating light in a nanometric volume at the apex of a metallic tip, sub-molecule-scale control of a basic photochemical reaction — phototautomerization — is now shown to be possible. Applicable to other photo-induced reactions, this technique signals a new strategy for the synthesis of complex molecules on surfaces.
