BALLESTEROS O., L. M  and  LONDONO, M. E. SURFACE MODIFICATION ON GOLD SUBSTRATES USING DIP PEN NANOLITHOGRAPHY TECHNIQUE. Rev. ing. biomed. [online]. 2014, vol.8, n.16, pp.26-32. ISSN 1909-9762.

In this work the effect of two types of tips A and M, over the patterns made on a gold substrate was explored. The patterns were built with a nanolithography, acrylic ink and gold substrate, disposing each tip with a triangular shape cantilever A-Frame (AF) on one side and a rectangular Dibbing Board (DB) cantilever on the other side. The patterns created by AF are more homogeneous than DB, this may be due to the rectangular shape of the DB which presents more ink concentration, because having a rectangular shape concentrates stress in the borders and the tip, having more possibilities to present ink adhesion in the borders of the cantilever and once the process begins with the creation of the pattern the ink merges with the substrate, depositing higher amount of ink in contrast with AF because it's triangular shape counts with only one zone where the stress focuses which leads to causes ink surplus.
