US Patent:
8361620, Jan 29, 2013
Filed:
Feb 13, 2006
Appl. No.:
11/353374
Inventors:
Hongmei Zang - Sunnyvale CA, US
Huiyong Paul Chen - San Jose CA, US
Denis Leroux - Salem MA, US
Rongchi Yu - Glenmont NY, US
Assignee:
SiPix Imaging, Inc. - Fremont CA

Control Of Reactor Environmental Conditions

US Patent:
2006001, Jan 26, 2006
Filed:
Jun 7, 2005
Appl. No.:
11/146920
Inventors:
Seth Rodgers - Somerville MA, US
A. Russo - Woburn MA, US
Sean LeBlanc - Westminster MA, US
Denis Leroux - Medford MA, US
International Classification:
C12P 1/00
US Classification:
435041000
Abstract:
The present disclosure generally relates to chemical, biological, and/or biochemical reactor chips and/or reaction systems such as microreactor systems, as well as methods for constructing and using such systems. In some cases, humidity control materials are utilized to provide beneficially high rates of gas exchange. The humidity control materials may be used, in certain instances, to provide at least adequate, and in certain embodiments superior, gas exchange for systems having small volumes. In some cases, 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 (for example, fluorinated) in some instances. In certain embodiments, a chip and/or a reaction system may be constructed so as to promote cell growth within it. In some embodiments, the chips may 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 certain embodiments, a reaction system is able to detect, measure and/or control an environmental factor such as the temperature, pressure, COconcentration, Oconcentration, relative humidity, pH, etc., associated with one or more reaction sites, by using one or more sensors, actuators, processors, and/or control systems. In certain embodiments, the present disclosure 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. In certain embodiments, the disclosed devices can employ light-interacting components suitable for use in reaction systems. These components may include waveguides, optical fibers, light sources, photodetectors, optical elements, and the like.
