RESUMEN
Stable, ultrathin DNA micropatterns were fabricated from photosensitive polymer diazoresin (DR) through a self-assembly technique. The micropatterns were achieved on LBL ultrathin film after UV exposure through a photomask. The patterns were characterized systematically with scanning electron microscopy, atomic force microscopy, X-ray photoelectron spectroscopy and fluorescence microscopy. All of the results indicate that the combined LBL self-assembly and photolithography technique is a promising method for constructing stable, well-defined micropatterns with a nanoscale thickness.
