In this work, different technological paths have been used & developed and characterized for the development of disposable microfluidic devices and lab-on-a-chip on plastic substrates. The developed technology will allow low cost manufacturing of polymer microstructures for numerous applications. So far, silicon and glass have been the two major substrate materials for the fabrication of lab-on-a-chip and opto-microfluidic devices. The disadvantages of these substrate materials are relatively high cost compared with plastic substrates, and high cost mass manufacturing, hampering the commercialization of these devices. Polymers are one of the good alternative low cost substrates and their mass fabrication methods have already been established for macro polymer structures. Different polymers e.g. poly dimethyl siloxane (PDMS), poly methylmetha acrylate (PMMA), poly propylene (PP), cyclic olefin copolymer (COC), hybrid polymer (Ormocer), off stochiometry thiolenes (OSTE) have been extensively developed for making plastic microstructures using UV lithography, soft lithography, embossing and imprinting, injection molding, micro injection moulding and direct laser writing.Plastic micro-reactor, micro capillary electrophoresis (-CE) and bio chips have been successfully developed and characterized using a number of these techniques and an overview of the main steps and results will be given in this presentation.
Dr. Akanksha Singh received her Ph.D from the University of Pune at Pune-INDIA in Physics in 2010. During her PhD thesis, she worked for six months (2008) in FRANCE at the FEMTO-ST Institute, CNRS, in the Micro Nano Science & System department. She then got the offer in the same Institute to work as a Research Scientist and continued her work till March 2012. From May 2012 she has been working as a Research Scientist in Micronova, Centre for Micro and Nanotechnology, FINLAND. Her research area focus in fabrication of micro/nano structured devices for various applications using different active and smart polymers.
