Abstract

A biosensor having a first conductive component is described, wherein the first conductive component includes at least one boundary formed by a first processing technique and at least one boundary formed by a second processing technique not the same as the first processing technique. The biosensor can also have a second conductive component including at least one boundary formed by the first processing technique and at least one boundary formed by a third processing technique not the same as the first processing technique. Further, the biosensor has a third conductive component including at least one boundary formed by the second processing technique and at least one boundary formed by the third processing technique not the same as the second processing technique.
