By means of a heated AFM probe we modify the material at high heating and cooling rates which allows to kinetically trap the high temperature state of the material, causing a fluorescence contrast between patterned and unpatterned areas. We demonstrate that this concept can be used to create complex features which have potential applications in anti-counterfeiting.Thermal scanning probe lithographyglassy supramolecular materialanti-counterfeitfast heatingtext::conference output::conference presentation
