Dip-pen lithography has been successfully demonstrated on mica substrates employing hydrosols of polyvinylpyrrolidone-capped Pd nanocrystals as well as Au nanocrystals stabilized by tetrakishydroxymethyl phosphonium chloride. Lines of widths as small as 30 nm and various aspect ratios have been successfully drawn by this method.
