The present invention provides a miniaturized integrated nucleic acid diagnostic device and system. The device of the invention is generally capable of performing one or more sample acquisition and preparation operations, in combination with one or more sample analysis operations. For example, the device can integrate several or all of the operations involved in sample acquisition and storage, sample preparation and sample analysis, within a single integrated unit. The device is useful in a variety of applications, and most notably, nucleic acid based diagnostic applications and de novo sequencing applications.
[ What is claimed is:] [1.] A miniature analytical device, comprising:a body having at least a first reaction chamber fluidly connected to a second reaction chamber by a fluid passage;a sample inlet, fluidly connected to said first reaction chamber, for introducing a fluid sample into said device;a
[ What is claimed is:] [1.] A miniature analytical device, comprising:a body having at least a first reaction chamber fluidly connected to a second reaction chamber by a fluid passage;a sample inlet, fluidly connected to said first reaction chamber, for introducing a fluid sample into said device;a differential pressure delivery system for maintaining said first reaction chamber at a first pressure and said second reaction chamber at a second pressure, said first pressure being greater than ambient pressure and said second pressure being greater than said first pressure, whereby when said second reaction chamber is brought to ambient pressure, said first pressure forces a liquid sample in said first reaction chamber into said second reaction chamber;a pressure source;at least first and second passages fluidly connecting said pressure source to said first and second reaction chambers, respectively;a first fluidic resistance disposed in said first passage between said pressure source and said first reaction chamber, said first fluidic resistance transforming a pressure from said pressure source to said first pressure;a second fluidic resistance disposed in said second passage between said pressure source and said second reaction chamber, said second fluidic resistance transforming said pressure from said pressure source to said second pressure; andfirst and second openable closures in said first and second reaction chambers, respectively, whereby opening of said first or second closures allows said first or second reaction chambers to achieve ambient pressure.
