  • Publication number: 20240118630
    Abstract: The present disclosure provides methods, device, and system for biochips manufacturing including a wafer processing apparatus such as a spin cell platform, a synthesizer, a wafer handling robot, an ultraviolet aligner, and a wafer centering device. The wafer processing apparatus uses a nozzle in a lid to disperse a solution to the surface of a wafer. Further, the wafer is positioned on top of a vacuum chuck and does not spin while the solution is dispensed over the surface of the wafer via surface tension, thereby permitting the first solution to react with a reagent on the surface. Further, when dispensing the first solution, a separation gap between the lid and the wafer is at a predetermined distance, for example, from about 20 micrometer to about 200 micrometer.

  • Publication number: 20230145978
    Abstract: A charging/discharging apparatus includes a base; a fixing base that is fixed and provided on the base; and a cover plate, wherein the fixing base includes an end plate; a connection member formed by extending from the end plate to the base and connected with the base; an opening provided on the end plate to perform charging and discharging; and an accommodation space formed by the connection member being recessed or formed by being surrounded by the connection member and the base, the cover plate is formed in an arch-shaped structure or a bending surface structure and includes an accommodation state in which the end plate is exposed and a covering state in which the end plate is covered, and when the cover plate is in the accommodation state, an end of the cover state which is close to the base is provided to be directed to the accommodation space.

  • Publication number: 20230092024
    Abstract: Disclosed herein is a substrate which includes a functional group protected with a photolabile group covalently attached to the substrate and a film of solvent thereof covering the substrate, where the thickness of the film is less than about 100 ?m. Also disclosed herein are methods of preparing such substrates. Further disclosed are methods of synthesizing polymers, methods of synthesizing arrays of polymers and methods of removing photolabile protecting groups. These methods all employ covering the substrate with a thin film of solvent where the thickness of the film is less than 100 ?m.

  • Patent number: 10822635
    Abstract: Methods for determining whether certain compounds, in particular crystals, are present in a sample of a biological fluid that indicates an individual has a particular disease or condition, such as but not limited to gout, pseudogout or urinary tract stones. In some embodiments, the methods include the steps of digestion and filtration of a sample of synovial fluid in order to isolate, if present, monosodium urate monohydrate (MSU), calcium pyrophosphate dihydrate (CPPD), or calcium phosphate crystals from the sample, wherein the filtrate is analyzed with a Raman device to ascertain the presence and type of the crystals. Devices for performing steps of the method are disclosed.

  • Patent number: 10307724
    Abstract: The present disclosure provides methods, device, and system for wafer processing. The wafer processing apparatus uses lid dispenser to disperse at least one reagent to the surface of the wafer. Further, the wafer is positioned on top of a rotatable vacuum chuck configured to spread at least one reagent over the surface of the wafer via a centrifugal force or surface tension, thereby permitting the at least one reagent to react with an additional reagent. Further, when dispensing the at least one reagent, a separation gap between the lid dispenser and the wafer is at a predetermined distance, for example, from 50 ?m to 2 mm.
