CONTROL OF REACTOR ENVIRONMENTAL CONDITIONS

摘要

The present disclosure generally relates to chemical, biological, and/or biochemical reactor chips and/or reaction systems such as microreactor systems (140), as well as methods for constructing and using such systems. Humidity control materials (150) are utilized to provide beneficially high rates of gas exchange. The humidity control materials (150) may be used, to provide at least adequate, and in certain embodiments superior, gas exchange for systems having small volumes. The currently disclosed materials include certain polymers, e.g., poly (acetylene) s such as poly (alkylacetylene) s. The polymers may be at least partially halogenated (e.g., fluorinated). In certain embodiments, a chip and/or a reaction system (140) may be constructed so as to promote cell growth within it. The chips may include one or more reaction sites. The reaction sites (142) can be very small, for example, with a volume of less than about 1 ml. In certain embodiments, a reaction system is able to detect, measure and/or control an environmental factor such as the temperature, pressure, CO2 concentration, 02 concentration, relative humidity, pH, etc., associated with one or more reaction sites (142), by using one or more sensors, actuators, processors, and/or control systems. The present disclosure also discloses materials and systems having humidity and/or gas control, for example, for use with a reaction system. Such materials may have high oxygen permeability and/or low water vapor permeability. The disclosed devices may employ light-interacting components e.g., waveguides, optical fibers, light sources, photodetectors, optical elements and the like suitable for use in reaction systems.
