The method is for preparing a sample in a microfluidic device. A microfluidic device is provided that has a first reservoir in fluid communication with a second reservoir in fluid communication with and adjacent to a draining unit that has a first absorbing member disposed therein. The first reservoir contains a first liquid that is held in the first reservoir by a capillary stop valve connecting the first and second reservoirs. The second reservoir has a sample support disposed therein. A second liquid, containing substances, is added to the second reservoir. The second liquid contacts the first liquid and the first absorbing member. The first absorbing member absorbs the second liquid and the first liquid. The substances adhere to the sample support.

Disclosed is a method of making a crack structure on a substrate, the crack structure being usable as a tunnelling junction structure in a nanogap device, including the controlled fracture or release of a patterned layer under built-in stress, thereby forming elements separated by nanogaps or crack-junctions. The width of the crack-defined nanogap is controlled by locally release-etching the film at a notched bridge patterned in the film. The built-in stress contributes to forming the crack and defining of the width of the crack-defined nanogap. Further, by design of the length of the bridge in a range between sub-&#x3bc;&#x3c0;&#x3b9; to &#x3e;25&#x3bc;&#x3b1;&#x3b9;, the separation between the elements, defined by the width of the crack-defined nanogaps, can be controlled for each individual crack structure from &#x3c;2 nm to &#x3e;100 nm. The nanogaps can be used for tunneling devices in combination with nanopores for DNA, RNA or peptides sequencing.
