Abstract: Provided herein are systems and methods for isolating a target from a biological sample. In some aspects, provided herein are automated systems and methods for isolating a target from a plurality of biological samples. For example, provided herein are automated systems and methods for isolating viral nucleic acid from a biological sample using a magnetic force to draw the nucleic acid out of a liquid biological sample.

Abstract: Provided herein are devices and methods for isolation and detection of an analyte from a sample. In some embodiments, provided herein are devices and methods of use thereof for vertical flow-based isolation and detection of analytes in a liquid sample, such as a urine sample.

Abstract: A molded article is disclosed. According to an embodiment, the molded article includes a blow-molded parison of material having an undercut formed in a surface of the parison of material. An apparatus for providing an undercut molding feature in a mold tool is also disclosed. According to an embodiment, the apparatus includes one or more undercut forming surfaces and an actuator pin that causes the one or more undercut forming surfaces to move to/from an undercut molding position or an undercut de-molding position. A method for providing an undercut molding feature in a mold tool is also disclosed. According to an embodiment, the method includes the step of moving an actuator to a position of engagement with one or more undercut forming surfaces to cause movement of the one or more undercut forming surfaces to/from an undercut molding position and an undercut de-molding position. A method for molding a molded article is also disclosed.

Abstract: A device for retaining a fluid is disclosed. The device includes a fuel tank having a multi-layer structure including an inner layer having a first surface that defines a cavity of the fuel tank, an outer layer having a second surface that defines a contour of the fuel tank, and a gas that is exposed to one or more of the first and second surfaces to define a fuel permeation barrier of the fuel tank. The gas seeps into one or more of the first and second surfaces to define the fuel permeation barrier having a depth. A method is also disclosed.
