Abstract:
1. A microfluidic system comprising: a first substrate having at least one microfluidic through-hole between first and second surfaces of the first substrate, the through-hole having a cross-section sufficient to retain a liquid therein; and a first substrate having at least one peak protruding from the second surface of the first substrate, the at least one through-hole of the first substrate being in fluid communication with the tip of the at least one peak; a second substrate having at least one microfluidic through-hole in a predetermined proximate spaced position and alignment with the at least one microfluidic through-hole of the first substrate, the at least one through-hole of the second substrate operable to retain the liquid displaced from the at least one through-hole of the first substrate thereto.
