    摘要: Various aspects of the present invention relate to light-interacting components suitable for use in chips and other reactor systems. These components may include waveguides, optical fibers, light sources, photodetectors, optical elements, and the like. If waveguides are used, they may be fashioned out of any material able to transmit light to or from the reaction site. The chip may contain a reaction site having a volume of less than about 1 ml. In some embodiments, the chip may be constructed in such a way as to be able to support a living cell. The chip may be used for imaging or analysis, or the chip may be used to facilitate a chemical or biological reaction, which may be light-sensitive or light-activated in certain cases. Other facilitated reactions may include the production or consumption of a chemical or biological species. In some embodiments, the chip may include more than one component or component type, or more than one reaction site.

    摘要: The present invention generally relates to chemical, biological, and/or biochemical reactor chips and other reaction systems such as microreactor systems, as well as systems and methods for constructing and using such devices. In one aspect, a chip or other reaction system may be constructed so as to promote cell growth within it. In certain embodiments, the chips or other reaction systems of the invention include one or more reaction sites. The reaction sites can be very small, for example, with a volume of less than about 1 ml. In one aspect of the invention, a chip is able to detect, measure and/or control an environmental factor such as the temperature, pressure, CO2 concentration, O2 concentration, relative humidity, pH, etc. associated with one or more reaction sites, by using one or more sensors, actuators, processors, and/or control systems. In another aspect, the present invention is directed to materials and systems having humidity and/or gas control, for example, for use with a chip. Such materials may have high oxygen permeability and/or low water vapor permeability. The present invention, in still another aspect, generally relates to light-interacting components suitable for use in chips and other reactor systems. These components may include waveguides, optical fibers, light sources, photodetectors, optical elements, and the like.

    摘要: The present invention generally relates to chemical, biological, and/or biochemical reactor microreactors and other reaction systems such as microreactor systems, as well as systems and methods for constructing and using such devices. In one aspect, a reactor on a chip has a container in fluid communication with a channel, and the channel is in fluid communication with a port for connecting the container to a source of fluid to be introduced into the container. The container can be very small, for example, with a volume of less than about 2 milliliters, and the fluid channel can have a channel volume of less than 1.5 percent of the container volume. According to another aspect, the combined volume of the port volume and the channel volume can be less than about 10 percent of the container volume. Such a configuration may increase the percentage of added fluid that reaches the container. In fed-batch operations, species may be added and removed via the same channel so that a gas headspace can be maintained within the reactor.

    摘要: Endoscopic instruments, such as endoscopes, and devices and methods for cleaning endoscopic instruments are provided. A cleaning device for use with an endoscopic instrument comprises an elongate member configured for advancement through an internal lumen within the endoscopic instrument and a cleaning member removably coupled to a portion of the elongate member. The cleaning element comprises a variable pressure region shaped and configured to increase the hydrodynamic fluid friction force and fluid pressure force of a cleaner or detergent against the wall of the internal lumen of the endoscope to more effectively clean all internal surfaces of an endoscopic instrument, including crevasses, scratches or other irregularities, without further damaging these surfaces.

    摘要: A nested temperature regulation device includes a watertight pouch having a gas valve, a first plurality of reactive spheres and a rupturable fluid bag. The first reactive spheres are configured to create an endothermic reaction or an exothermic reaction for a set period of time when engaged by the fluid. At least one soluble barrier is positioned within the pouch and includes a hollow interior space that contains another plurality of reactive spheres. Each soluble barrier is constructed to dissolve and to permit the fluid from the bag to engage a subsequent plurality of reactive spheres after a predetermined period of time that is equal to the effective reaction time of the plurality of reactive spheres immediately previously engaged by the fluid. One or more of the plurality of reactive spheres includes a coating that delays the fluid from accessing the reactive material of the sphere having the coating.
