Abstract:
Microfluidics is a research field that is gaining a lot of attention in recent years, due to the reduced costs and increased efficiency of all the instrumentation based on this technology, including optical-based one. Due to that, the necessity to bond interesting optical materials, such as KLu(WO4)2 crystals in our case, to the most commonly used materials in microflui-dics, like PDMS and glass, to produce optical-based microfluidic devices, is increasing as well. In this work, different strategies to bond PDMS to PDMS and PDMS to glass will be opti-mized and compared with two of the most used direct bonding techniques such as oxygen plasma treatment and partial curing of PDMS. In addition, oxygen plasma treatment will be adapted to bond PDMS to KLu(WO4)2 in order to fabricate optical-based microfluidic devices. Moreover, mechanical properties of Sylgard 184 PDMS from Dowsil such as Young Modulus and Ultimate Tensile Stress will be studied to clarify the reported bibliography based on PDMS.
