Patent ID: 7504070

Claim:
A micro reactor comprising: a first substrate comprising a predetermined number of elongated reactors, at least two corresponding micro channels connected to each reactor at respective connection points, at least one injection port corresponding to each reactor, the injection port feeding/receiving a sample solution to said reactor and being disposed at an end of one of the corresponding micro channels or the reactor connected to the corresponding micro channels, and at least one discharge port corresponding to each reactor, the discharge port recovering the sample solution after a reaction in the reactor, the discharge port being disposed in one of the corresponding micro channels or the reactor connected to the corresponding micro channels; and a second substrate comprising: at least one micro pump being integrally formed therein, said micro pump comprising a cavity defined by an inner surface of the substrate, an inlet associated with the cavity, and a piezoelectric operation section formed on an outer surface of the substrate, the piezoelectric operation section including an electrode and a piezoelectric layer formed on an outer surface of the substrate, an injection connection port for feeding the sample solution to the injection port, and a discharge connection port for receiving the sample solution from the discharge port, wherein the first substrate and the second substrate are integrally bonded in such a manner that the injection connection port and the discharge connection port of the second substrate align with the injection port and the discharge port of the first substrate, respectively, and wherein a pressure generated in the cavity by the piezoelectric operation section moves the sample solution through the reactor, and wherein the micro pump is associated with one of the injection connection port and the discharge connection port.
