  • Patent number: 10300450
    Abstract: The present disclosure provides apparatuses, systems, and methods involving a spotter for depositing a substance on a submerged surface. The spotter comprises an outlet cavity defined at least in part by a spotting orifice, a first opening, and a second opening. The spotter also comprises a first conduit fluidly coupled to the first opening and a second conduit fluidly coupled to the second opening. The spotter is adapted so that fluid flowing through the first conduit and the second conduit is communicated among the first opening, the second opening, and a submerged deposition surface when the sealing orifice is sealed against the submerged deposition surface to form a deposition spot on the submerged deposition surface. The submerged deposition surface is within a liquid such that the liquid covers the deposition spot upon removal of the orifice from the deposition surface.

  • Patent number: 8846310
    Abstract: Methods of preparing assays and of assaying, using substantially self-contained, portable, user-initiated fluidic assay systems. Example assays include diagnostic assays and chemical detection assays. Diagnostic assays may include, without limitation, enzyme-linked immuno-sorbent assays (ELISA), and may include one or more sexually transmitted disease (STD) diagnostic assays. An assay system may include one or more fluid chambers, one or more fluid paths amongst the fluid chambers and/or between the fluid chambers, a sample portion, and/or an assay portion. The assay system may include a fluid controller system to dispense fluid from the one or more fluid chambers, and a user-initiated actuator to control the fluid controller system. The fluid controller system may be configured to dispense fluids serially, and may be configured to mix a plurality of fluids. The user-initiated actuator system may include an external user-operated trigger mechanism.

  • Patent number: 8846129
    Abstract: A method of forming of biological sensing structures including a portion of a substrate is recessed to form a plurality of mesas in the substrate. Each of the plurality of mesas has a top surface and a sidewall surface. A first light reflecting layer is deposited over the top surface and the sidewall surface of each mesa. A filling material is formed over a first portion of the first light reflecting layer. A stop layer is deposited over the filling material and a second portion of the first light reflecting layer. A sacrificial layer is formed over the stop layer and is planarized exposing the stop layer. A first opening is formed in the stop layer and the first light reflecting layer. A second light reflecting layer is deposited over the first opening. A second opening is formed in the second light reflecting layer.

  • Patent number: 8821957
    Abstract: The invention concerns in particular a method for depositing a nanometric multilayer thin film on a substrate from a liquid solution containing at least one surfactant. The method includes the following steps: forming a film from the solution; contacting the substrate; and depositing the film on the substrate. The invention is particularly formed to enable depositing black films on different types of surfaces, in particular for obtaining highly organized films. The films obtained by the method are particularly useful in electronics and optics.

  • Patent number: 8802008
    Abstract: An automatic analyzer for analyzing samples, such as urine and blood, is adapted so that analysis measured values are not affected by carry over by a repeatedly used dispensing nozzle. Coating the surface of the dispensing nozzle with a chemisorbed polyethylene glycol derivative forms a molecular layer that inhibits the adsorption of biopolymers, to reduce carry over by the dispensing nozzle.

  • Patent number: 8802183
    Abstract: The system of the present invention includes a conductive element, an electronic component, and a partial power source in the form of dissimilar materials. Upon contact with a conducting fluid, a voltage potential is created and the power source is completed, which activates the system. The electronic component controls the conductance between the dissimilar materials to produce a unique current signature. The system can also measure the conditions of the environment surrounding the system.

  • Patent number: 8802024
    Abstract: A method for manufacturing a biochip is provided. First, a first self-assembled monolayer is coated on a substrate. Next, a plurality of first biomedical molecular dots are formed on the first self-assembled monolayer by micro-titration technique. After the bonding reaction between the first biomedical molecular point and the first self-assembled monolayer, a second self-assembled monolayer is deposited on the surface of the first self-assembled monolayer by evaporation. The second self-assembled monolayer attached on the plurality of first biomedical molecular dots and the first self-assembled monolayer not bonded to the substrate are removed, so that the first biomedical molecular dots immobilized on the first self-assembled monolayer are exposed. Finally, a second biomedical molecular layer is immobilized on the exposed portions of the first biomedical molecular dots.

  • Patent number: 8784928
    Abstract: Methods for the deposition of silver-comprising films on nonconducting substrates, and, more particularly, to deposition of such films that are very thin, are provided. The surface of nonconducting substrates is modified with a superabsorbent polymer to increase silver deposition when compared to a non-modified surface. Also provided are films produced using a swelling agent, whereby porosity of the surface of the nonconducting substrate is increased, thereby permitting increased silver deposition when compared to an unmodified surface.

  • Publication number: 20140199468
    Abstract: A nanofiber is formed by combining one or more natural or synthetic polymeric materials and one or more than one cross-linking agents having at least two latent reactive activatable groups. The latent reactive activatable nanofiber may be used to modify the surface of a substrate by activating at least one of the latent reactive activatable groups to bond the nanofiber to the surface by the formation of a covalent bond between the surface of the substrate and the latent reactive activatable group. Some of the remaining latent reactive activatable group(s) are left accessible on the surface of the substrate, and may be used for further surface modification of the substrate. Biologically active materials may be immobilized on the nanofiber modified surface by reacting with the latent reactive groups that are accessible on the surface of the substrate.
