Laser implantation of dicyanoanthracene in poly methyl methacrylate/from a 100-nm aperture micropipette

Implantation into poly methyl methacrylate.films has been achieved using a dicyanoanthracene DCNA. doped 100-nm aperture micropipette excited with a pulsed laser. The distribution of implanted DCNA was observed on the film surface using a fluorescence microscope. The measured implanted area had a diameter of less than 600 nm demonstrating that organic molecular implantation into the surface of a polymer film with spatial resolution in the submicrometer range is now possible. q2000 Elsevier Science B.V.
