Bacteriologic cultivation on a fluorocarbon-resin FEP surface has been successfully demonstrated by a photochemical modification method using an ArF excimer laser and a boric-acid aqueous solution. The resin surface was photochemically defluorinated with boron atoms which were produced by the photodissociation of the boric-acid aqueous solution; dangling bonds of carbon atoms in the surface were bonded with OH radicals which were also produced by the photodissociation. The sample surface was area-selectively modified into hydrophilic property by the exposure of ArF excimer laser with a mask-pattern image. A culture medium of the Czapeck-dox agar was fabricated on the hydrophilic parts, and a mold was cultured in the agar at 25°C and 7 days.
