  • Publication number: 20250144621
    Abstract: A microfluidic device is disclosed. The microfluidic device includes a silicon layer having a first channel formed in a first side of the silicon layer and a second channel formed in a second side of the silicon layer. The silicon layer has a vertical connection extending through the silicon layer. The microfluidic device further includes a bottom wafer bonded to the first side of the silicon layer to cover the first channel. The microfluidic device further includes a glass wafer bonded to the second side of the silicon layer to cover the second channel. The microfluidic device further includes an electronic component integrated into the silicon layer.

  • Publication number: 20240390874
    Abstract: According to aspects, the invention is embodied as a method of performing chemical reaction screening steps using a microfluidic device, which includes a microreactor. The latter is defined at an intersection of a first channel and a second channel of the microfluidic device. The first channel is fenced by two size-selective filters, at the intersection. The two size-selective filters include a first filter and a second filter, which are respectively arranged upstream and downstream of the microreactor in the second channel. The method revolves around sequentially performing chemical reaction screening steps according to distinct combinations of pairs of chemical compounds, where each of the pairs involves a first chemical compound and a second chemical compound. Beads are fed into the microreactor and a solution is flown through the microreactor. The beads are fed into the microreactor through the first channel, such that they remain confined between the two size-selective filters.

  • Patent number: 10564091
    Abstract: An optical sensing device includes a substrate; a first dielectric layer extending thereon; a plurality of pairs of opposite antennas patterned on the first layer; and a second dielectric layer that covers all of the antennas. Opposite antennas are, in each of the pairs, separated by a gap g, which, on average, is between 1 nm and 50 nm, as measured in a direction x parallel to a main plane of the substrate. The pairs of antennas have different geometries. The second layer covers all the antennas and defines an electro-magnetic field enhancement volume between the opposite antennas of each of the pairs, thanks to the gap. Electro-magnetic radiation can be concentrated in each volume, making it possible to optically sense an analyte via opposite antennas of each of the pairs. Such a device allows analytes to be funneled and guided into the field-enhanced volumes for deterministic sensing.
