Miniaturization of sensing technology has led to the development of multifunctional micro total analysis systems (μTAS) that benefit from microfluidic technology. Optical sensing is one of the most commonly used sensing approaches integrated into μTAS devices and features high sensitivity and low detection limits. Different materials have been used for the fabrication of μTAS devices, each having their advantages and disadvantages. Herein, a high-aspect-ratio optofluidic waveguide fabricated from SU-8 is presented for the first time. The suitable optical properties and chemical inertness of SU-8 provide a durable device made by a flexible and cost-efficient fabrication process. The optofluid..
