| Background and description More specifically, the lotus leaf project includes: (i) preparation of micro- and nanopatterned surfaces using different techniques (ii) their topographical and chemical characterization, and (iii) pointing out and exploring possible applications The project is a close collaboration between the Dept. of Applied Physics and the Dept. of Electrical Engineering at Chalmers and GU. This is an example of collaboration between the Biocompatible Materials and the ELIS (also SSF) programmes. Scientific results 
The major result up to now, is the preparation of super-hydrophobic polymer
(PDMS) surfaces by pulsed laser treatment. Micro- and nanofabrication has been
combined to prepare micropatterned silicon samples that are used as templates
for the molding of PDMS. The polymer samples are characterized by optical and
electron microscopy, interferometry, AFM, contact angle and XPS. Electrical
measurements to test the long-term durability are initiated. The typical
sample size in this project is many square centimeters and the technique
also enables the use of non-flat surfaces. Two papers are in preparation
and the project will end in June 2005.
