Patent number: 11376582Abstract: Fabricating a fluid testing device includes receiving a substrate, and applying a pattern of hydrophobic material to the substrate. The substrate is positioned between layers of a thermally reflective material. Heat and pressure is applied to the substrate and thermally reflective material to reflow the pattern of hydrophobic material. A protective coating is applied over a portion of the substrate to form the fluid testing device.Type: GrantFiled: March 5, 2019Date of Patent: July 5, 2022Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Jaione Tirapu Azpiroz, Matheus Esteves Ferreira, Ademir Ferreira da Silva, Ricardo Luis Ohta, Mathias Steiner

Patent number: 11060968Abstract: A target sample to be chemically analyzed is received at a microfluidic device which is part of an analysis card. The microfluidic device includes at least one input layer configured to receive the target sample, at least one intermediary layer, and at least one readout layer configured to present one or more color attributes at one or more readout regions in response to one or more colorimetric reactions to the target sample. An image of the readout layer of the microfluidic device is obtained. A calibration file that corresponds to the analysis card is obtained. The calibration file includes a calibrated model of at least one color attribute based on data from at least one known chemical attribute of at least one standard sample processed by a calibration card.Type: GrantFiled: March 30, 2018Date of Patent: July 13, 2021Assignee: International Business Machines CorporationInventors: Ricardo Luis Ohta, Ademir Ferreira da Silva, Andre de Oliveira Botelho, Matheus Esteves Ferreira, Jaione Tirapu Azpiroz, Michael Engel, Mathias Steiner

Patent number: 10605826Abstract: A calibration apparatus for a tip-enhanced Raman microscope includes a substrate; a two-dimensional Raman scatterer that is mounted on an upper surface of the substrate; and a well-defined topographic structure that is formed at the upper surface of the substrate. The topographic structure may include convex geometric shapes such as triangles and squares arranged in one or more periodic lattices. Calibration is via adjusting a focal length of a laser beam until a signal from a spectrometer repeatedly exhibits a stepped response when a focal point of the laser beam traverses an edge of a two-dimensional Raman scatterer, then adjusting the relative lateral positions of a scanning probe microscope probe tip and the focal point until the signal from the spectrometer and a signal from the scanning probe microscope repeatedly change within an acceptable time delay while the focal point and the probe tip traverse edges of the topographic structure.Type: GrantFiled: June 17, 2018Date of Patent: March 31, 2020Assignee: International Business Machines CorporationInventors: Michael Engel, Mathias Steiner, Ado Jorio de Vasconcelos, Cassiano Rabelo, Luiz Gustavo Cancado, Hudson Miranda
