Abstract
The illustrated invention defines an analytical chip comprising an optically transparent substrate such as glass or silicon that defines a fluid inlet port and at least one fluid carrying channel communicating with the inlet. At least one reaction chamber fluidly communicates with the channel and an air management chamber is in fluid communication with the reaction chamber to facilitate capillary flow of fluid into the reaction chamber.
