    摘要： Disclosed is a microneedle biosensor and a manufacturing method for same, the microneedle biosensor comprising: a working electrode that comprises a circular thin-film first base, a plurality of microneedles protruding vertically upwards from the first base, and first wiring extending from one side of the circumference of the first base; a counter electrode that comprises a second base which is a three-quarter circle strip thin-film that is concentric with the first base and separated by a set distance from the circumference of the first base, a plurality of microneedles protruding vertically upwards from the second base, and second wiring extending from one side of the second base so as to be disposed on a level with the first wiring; and a reference electrode that comprises a third base which is a quarter circle strip thin-film that is separated by a set difference from the other side of the second base, is concentric with the first base and is separated by a set distance from the circumference of the first base, a plurality of microneedles protruding vertically upwards from the third base, and third wiring extending from one side of the third base.

    摘要： Disclosed are electrode arrays and methods of focusing charge density (voltage or current) at a functional surface on electrode arrays. An example method comprises: a. providing an electrode array comprising: i. a support substrate; ii. at least one surface structure protruding from an upper surface of the support substrate wherein the surface structure includes an electrode layer; iii. a functional surface on the electrode layer, wherein the functional surface is on an upper portion of the at least one surface structure and wherein the functional surface is adapted to contact an active species in a conductive solution; b. exposing the surface structure to the conductive solution comprising an active species, in which a counter electrode is positioned; c. establishing a current or voltage between the functional surface on the electrode layer and the counter electrode such that the charge density is focussed at the functional surface on the electrode layer.
