Two in one fell swoop: With a confocal microscope and a Ti:Sa fs‐laser, gold nanoparticle‐containing micro‐ and nano‐sized patterns can be written into 350 nm thin sol–gel derived silicate‐titanate films (see figure). The nanoparticles are characterized by a multiphoton‐induced luminescence and enhance the Raman scattering of adsorbed adenine molecules by the SERS effect.
