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.
