Attenuated Total Reflection Fourier Transform Infrared (ATR FT-IR) Spectromicroscopy Using Synchrotron Radiation and Micromachined Silicon Wafers for Microfluidic Applications
Authors: T Morhart, S Read, G Wells, M Jacobs, S Rosendahl, S Achenbach, I J Burgess
This paper describes a custom-designed optical configuration for ATR FT-IR spectroscopy and imaging applications in microfluidic devices, compatible with the IRUBIS ATR Crystals. Results show that our crystals are highly compatible with standard photolithographic techniques. ATR FT-IR mapping as a function of sample position across the channel illustrates the potential application of this approach for rapid prototyping of microfluidic devices.

Subwavelength Structures for Interference Enhanced Attenuated Total Reflection Spectroscopy and its Application for Blood Analysis
Authors: L Sykora, A Müller, A Roth, S Kondratiev
Attenuated total reflectance (ATR) infrared absorption spectroscopy is a well-established analytical method. However, the sensitivity is limited compared to transmission measurements by the penetration depth of the evanescent wave. Innovative ATR Crystals with subwavelength pillars were made from silicon. First experiments show an enhancement factor of up to 20 compared to a standard single reflection diamond ATR element.
