Increasing demand of integrated microfluidic device fabrication technologies fosters emergence of novel prototyping methods in transparent optical materials. Recent progress in the development of ultra-short pulse laser enabled formation of light induced material damage in the in thermally crosslinked elastomer polymethyldisiloxane (PDMS) with a micrometric spatial resolution. These modifications will be used for integrated micro-optical elements as well as for various microfluidic systems.
The goal of this practice is to obtain the ultra-short pulse laser exposure conditions for efficient formation of modification in the PDMS volume in order to form three-dimensional microstructures. During the practice, it is planned to select femtosecond laser exposure conditions causing different types of modification on the surface and in the volume of PDMS. Simple micro optic and microfluidic devices will be realized and characterized employing optical microscopy and micro computed tomography techniques.
Project is funded by EU Structural Funds according to the 2014–2020 Operational Programme for the European Union Funds’ Investments priority “Development of scientific competence of researchers, other researchers, students through practical scientific activities” under Measure No. 09.3.3-LMT-K-712.
At the end of the practice, a manual on laser microstructure formation in the bulk of PDMS will be prepared and an abstracts will be prepared and presented at the conference.
