Abstract
A method of making a dielectric substrate array for conducting a plurality of reactions in parallel in a number of wells, the method comprising: forming a first passage and a second passage each extending through a dielectric substrate, the substrate having a first surface and an opposing second surface; forming a plurality of channels on said first or second surface, including a first channel, a second channel, a third channel and a fourth channel on the substrate, wherein the first channel is on the first surface and intersects with the first passage, wherein the second channel is on the second surface and intersects with both of the first passage and the second passage, wherein the third channel is on the first surface and intersects with the second passage, wherein the fourth channel is on the first surface and is located between the outlets of the first and second passage at the first surface, and wherein (a) the connected first channel, first passage, second channel, second passage and third channel define a cross-over channel having dimensions suitable for promoting capillary action and (b) the fourth channel defines another channel having dimensions suitable for promoting capillary action; forming a plurality of reservoirs in a surface of the substrate, each connected to a channel, with one of the reservoirs connected to the first channel; and bonding a first plate to the top surface of the substrate and a second plate to the bottom surface of the substrate, thereby enclosing the channels, wherein the cross-over channel crosses over from the first surface to the second surface via the first passage and back to the first surface via the second passage and thereby avoids intersecting with the fourth channel located on the first surface.
