Selective inhibition of the polymerization leads to sub-diffraction feature sizes in direct writing lithography—a principle based on the idea of stimulated emission depletion (STED) microscopy. However, the detailed understanding of the inhibition process is a key point to further enhance the resolution of the system. The authors present experiments focused on the time dynamics of the inhibition process, clarifying possible photophysical pathways.
