In droplet microfluidics, the pairing of droplets in parallel channels is sometimes required, e.g. to control their encounter and to promote their coalescence. Prakash and Gershenfeld [1] showed that passive synchronization could be achieved with bubbles in a ladder-like channel network. Bubbles flow in the rails and induce recirculation in the interconnecting rungs, which supposedly provides the feedback and subsequent synchronization. Ahn et al. recently extended this study to trains of droplets in flow-rate-driven conditions [2]. We here present an extensive experimental and theoretical investigation of droplets synchonization in multiple parallel channels. Droplets are produced with independent flow-focusing structures. Several experimental conditions are tested, including several geometries (and subsequent flow resistance) and inlet conditions (pressure-driven vs. flow-rate-driven). An extension to three rails is also considered. The microfluidic chips are designed with the help of a lumped-element model in which droplets are driven by the flows. [1] M. Prakash and N.

We developed a microfluidic device for the detection of bio-molecules. The active part of the device is a biofunctionalized interdigitated capacitive sensor. The microsystem consists of a sensor on silicon chip, a microfluidic channel formed by photo-patternable resist and a plastic cover. We implemented a low temperature packaging process to assemble the sensor and prevent the biological material from degradation. [less ▲]

Influenza A viruses cause annual epidemics and occasional pandemics that spread worldwide. The nucleoprotein is essential for the survival of this virus and is thus well-conserved. We developed a quantitative electronic biosensor displaying a protein recognition thanks to the covalent grafting of anti-nucleoprotein antibodies. The detection device lies on interdigitated array microelectrodes (IDAM), covered with alumina (Al2O3) to protect the underlying aluminum and enhance the electrical coupling. As the dimensions of the IDAM can determine the sensitivity of the sensor, we processed 4 structures with varying electrode widths and spacings in the same silicon chip and assessed their individual performance. The sensing area of each sensor is 200*200 µm2 and the overall chip-size is 3*3 mm2. The sensor is mounted in a DIL-16-package partially encapsulated by resin. [less ▲]

We developed a method of assembly for electrical micro-bio-sensor. The system is a part of a micro-fluidic device based on a capacitive biosensor. The bio-sensor is designed for bio-molecules (specifically DNA and protein) detection, quantification and recognition. Using the developed method we assembled series of fully functional demonstrators. [less ▲]
