Microcontact Printing of CdS/Dendrimer Nanocomposite Patterns on Silicon Wafers


  • We thank Dr. Christina Wege, Department of Biology, Stuttgart University for help with recording luminescence patterns.


Micrometer-scale patterns of blue photoluminescing CdS nanoparticles can be produced by microcontact printing on a hydroxyl-terminated silicon wafer surface (see Figure). The CdS nanoparticles were synthesized with amine-terminated generation eight dendrimers as stabilizers. The resulting CdS/dendrimer composite is directly printable due to hydrogen bonds between dendrimer and surface.
