Abstract:
1. A detection device for identifying a target substance or substances, comprising: a first substrate; a second substrate facing the first substrate, wherein at least one of the first substrate or the second substrate includes at least one of an electrically-conductive material or a semi-conducting material; an insulating member positioned between the first substrate and the second substrate; a gap positioned between the first substrate and the second substrate, wherein the gap is configured to receive a sample containing the target substance or substances; and a current decreasing member configured to decrease leakage current across the first substrate and the second substrate; wherein the current decreasing member includes a first insulative material positioned on a surface of the first substrate and along the gap and a second insulative material positioned on a surface of the second substrate and along the gap, wherein the first insulative material forms an entire edge of the gap nearest the first substrate, and wherein the second insulative material forms an entire edge of the gap nearest the second substrate.
