The development of miniaturized structures on or below the surface of glass is an issue of present research. Femtosecond-laser-radiation combined with the two photon process is a promising approach to push the written structures towards the nanometer scale. Here we used the photosensitive glass FS21 with its three step photoform process (irradiation, annealing, HF-etching). For the irradiation we used a TiSa oscillator only. These structures and steps are developed to realize a distinct miniaturization of glass components and to improve biocompatibility for specific cells. This structured glass is interesting for microfluidic and lab-on-a-chip devices. Here we present new scientific findings to material characterization and the photoform process.
