Abstract:
1. A method, comprising applying a biological fluid to an integrated microreactor comprising: a semiconductor material body having a surface; a buried channel extending in said semiconductor material body at a distance from said surface, and having a first and a second end; a first and a second trench extending from said surface respectively as far as said first and second ends of said buried channel, and being in fluid connection with said buried channel; a reservoir region formed on the surface of the semiconductor material body, extending above said surface and defining a first and a second reservoir connected to said first and second trenches, respectively; wherein the biological fluid is applied to the first reservoir and travels via the first trench to the buried channel where a biological test is performed, and wherein the biological fluid then travels via the second trench to the second reservoir.
