Figure 2From: A nanoporous interferometric micro-sensor for biomedical detection of volatile sulphur compounds The microfluidic nanoporous reflective interferometric RIfS device. Photo with schematic representations of the embossing stamp and integrated AAO sensing platform within the microfluidic structure. Top photo shows the nanoporous microchip RIfS device, including the PMMA base chip bearing, the embossed microfluidic structure and the bondless device clamp. An enhanced view of the microstructures showing the position of nanoporous alumina and the micro-pillar mixer is clearly presented (bottom right).Back to article page
