    摘要: Devices having channels where one end of the channel has a dead-end formed of a gas permeable, but fluid resistant material (e.g., material that is substantially liquid impermeable) are provided. The devices can be manufactured using methods employing photolithography techniques similar to those used in semi-conductor manufacture. In other aspects, methods are provided for transferring a sample such that fluid can be drawn to the dead-end of a fluid channel by injecting, adding, or otherwise placing a sample at one end of the channel and by applying pressure, such as negative pressure via a vacuum, to the gas permeable material via another channel or port that is spaced apart from the dead-end containing fluid channel. Application of a positive or negative pressure to another recess in the gas permeable housing that is spaced away from the fluid channel causes a pressure change within the fluid channel, thereby drawing fluid across the channel to the dead-end of the channel.
