Abstract
A capillary driven microfluidic system and a biosensing device including the capillary driven microfluidic system are provided. The capillary driven microfluidic system includes: a first substrate comprising at least one microfluidic channel ending in an opening, and having, adjacent to the opening, a protruding element; and a second substrate comprising at least one open cavity. The at least one protruding element and the at least one cavity include at least one hydrophilic surface. In addition, the at least one protruding element and the at least one cavity may be adapted for engaging with one another for providing transfer of a fluid between the first substrate and the second substrate. A space between the at least one hydrophilic surface of the at least one protruding element and the at least one hydrophilic surface of the at least one cavity is provided, where the separation between said surfaces is such that capillary forces are generated on the fluid upon entering inside the space.
