Optofluidic micro-sensors for the determination of liquid concentrations

We present a novel optofluidic device for non-invasive and label-free determination of liquid concentrations. A microfluidic channel filled with the sample solution is hit by laser light in an angle close to the critical angle for total internal reflection. Due to the intentionally defined divergenc...
