Multilayered planar sensor for detection of materials including specific dna or dna-like strands

A method of drawing single-stranded DNA strands to a sensor for sensing presence of specific single-stranded DNA strands, wherein the sensor comprises a substantially planar electret layer, the electret layer having a positive pole that is configured to attract negatively charged particles;

• a sensing layer configured above the electret layer, the sensing layer including a plurality of sensors comprising pairs of conductive elements with gaps therebetween, wherein strands of single-stranded DNA of the sensor are configured within the gaps, wherein the strands of single-stranded DNA of the sensor within the gaps are configured to couple with strands of single-stranded DNA from the biological sample;
• and a solution layer configured above the sensing layer, said solution layer comprising chemical solutions for breaking down a biological sample into DNA strands;
• and the method comprises:
• breaking down the biological sample into single-stranded DNA of the sample in the solution layer;
• and
• drawing the single-stranded DNA of the sample from the solution layer to the sensing layer with the positive pole of the electret layer.

A method of manufacturing a multilayered sensor device, comprising:

• providing a substrate layer;
• cutting a plurality of sheets of electret material, and laminating the plurality of sheets of electret material onto the substrate layer to thereby form a plurality of electret layers;
• heating and applying an electric field to each electret layer to thereby pole the electret material;
• laminating a sensing layer onto each separation layer, the sensing layer including a plurality of pairs of conductive elements with gaps therebetween;
• configuring strands of single-stranded DNA of the sensing layer within the gaps;
• and
• laminating a solution layer above the sensing layer, the solution layer comprising chemical solutions for breaking down a biological sample into DNA strands of the sample.
