In this article, our recent results of the application of near‐field scanning optical microscopy (NSOM) to the photochemistry in small domains and single polymer nanoparticles are presented. After an introduction and the description of our apparatus, results on three topics are presented: (1) Control and observation of a photoacid generation from p‐nitrobenzyl 9,10‐dimethoxyanthracene‐2‐sulfonate (NAS) in a polymer thin film, (2) Patterning due to refractive index changes by a photoisomerization of 3‐phenyl‐2,5‐norbornadiene‐2‐carboxylic acid (PNCA) (3) NSOM observation of moving nanoparticles at a liquid/solid interface.
