Securing functionality of lab-on-a-chip devices
Microfluidic lab-on-a-chip systems, short LOC, implement a multitude of ocurring processes on the smallest of spaces. Lab on a chip analyze liquids on a compact chip for process analytics of biological, chemical or physical processes. Lab on a chip use the capillary force for transporting a few picoliters or microliters of a fluid. Using dedicated microscope-based surface metrology like the TopMap profilers, allows you for checking for dimensional tolerances of the microfluidic LOC channel, evaluate the lab-on-a-chip channel depth or width with high precision, determine the volume or measure the flatness areally on the entire microship. If parallelism, step height or flatness of the chip lab are not within the very tight tolerances and according to specification, this will affect the performance and reliability of the chip lab analysis.
