Abstract
A microfluidic structure assembly having a microchannel formed by bonding two plates together is disclosed. The microfluidic structure assembly includes a first plate and a second plate. At least one of these plates has one or more microgrooves. Microdepressions and microprojections are also present in the plates and they connect such that the microprojections of one plate fit into the microdepressions of the other plate. As a result, the two plates are proximate to each other to form an assembly in which the microgrooves to form microchannels. These microdepressions and microprojections securely lock the microchannels into desired positions. Preferably the plates are made by molding to form the microdepressions, microgrooves, and microchannels.
