摘要:
An electrochemical cell in the form of first and second sheet members (2, 12) at least one of which is gas permeable on which is disposed one or more planar electrodes (4, 6, 8). Peripheral regions of the first and second sheet members (2, 12) are sealed together to form a sealed envelope or reservoir containing electrolyte. Electrical connection means (41, 61, 81) extend from each of the electrodes (4, 6, 8) across the sealing of the sheet members (2, 12) to provide external electrical connection.

摘要:
The present invention is to detect leakage of fluid from a channel in a microreactor certainly at an early stage. A chemical reactor has a microreactor with a pump for sending first, second solutions, and a channel for mixing and reacting the first, second solutions. The solution sending amount of the first, second solutions to be supplied to the microreactor is controlled by a pump controlling device. The microreactor has a first substrate with a channel and a second substrate to be bonded airtightly with the first substrate. A leak detecting channel is formed in the vicinity of the channel in the first substrate.

Microfluidic fraction collectors fractionating a sample stream into discrete sample volumes are provided. Fluid flow control mechanisms (22, 24, 26, 112, 114, 116, 492, 716A-716E) divert selected portions of a sample stream from an inlet channel (707) into one or more branch channels (708-712). The fluid flow control mechanisms may be passive, relying on sample volume and fluidic impedance to establish the sample collection sequence. Alternatively, active fluid flow control mechanisms may be controlled, with or without feedback, to establish the sample collection sequence.
摘要:
The present invention is directed to materials and reactor systems having humidity and/or gas control. The material may have high oxygen permeability and/or low water vapor permeability. In some cases, the material may have sufficient permeance and/or permeability to allow cell culture to occur in a chip or other reactor system using the material. In certain embodiments, the material may be positioned adjacent to or abut a reaction site within a chip or reactor; in other embodiments, the material may be positioned such that it is in fluidic communication with the reaction site. The material may also be porous and/or transparent in some cases. In one set of embodiments, the material include a polymer that is branched, and/or contains bulky side groups that allow the polymer to have a more open structure. In some cases, the material may include two or more layers. Each layer may have a desired property, which may include, for example, permeability, transparency, cytophilicity, biophilicity, hydrophilicity, or a structural feature. In some embodiments, the material may be chosen so as to promote cell growth within the chip or reactor.
