Abstract:
Nanoscience and nanotechnology research is strongly encouraged and developed nowadays due to its positive impact on the development of new areas such as nano-biology, nano-electronics, nano-photonics and micro- and nano-fluidics. The requirements of these new scientific domains have prompted the emergence of innovative techniques for obtaining structures with dimensions under micrometer range. To meet the high resolution and reproducibility conditions, several nanostructure methods for processing of materials’ surfaces have been proposed and tested in recent years: Electron beam or ion beam lithography, X-ray lithography, Direct Laser Writing (DLW). In this paper we present our experimental results showing an increased efficiency compared to other techniques of structuring the metal surfaces. These results are based on laser micro- and nano-processing. We developed a technique which could be used to achieve a fingerprint system for biological polymeric materials and other applications in micro- and nano-fluidics.
