Abstract: Conventional spectroscopy used in the life sciences and analytical chemistry is performed by spectrophotometer - bench top equipment which is expensive, bulky and demanding large volume of sample and reagents. Miniaturization of spectrometer and sample preparation cuvette calls for a micrototal-analysis system (uTAS) or lab-on-a-chip (LOC) which integrates spectrometer capabilities and microfluidics into a single platform. Such LOC can benefit from various optical microcomponents capable of focusing, dispersing, guiding light to the desired point in order to achieve a highly sensitive and robust spectroscopy measurement at a low cost as well as reducing reagent usage. Poly(dimethylsiloxane) (PDMS) has been widely used for the fabrication of microfluidics and LOC devices due to unique characteristic such as biocompatibility, low cost, and rapid prototyping capability by soft lithography.
