1. A microneedle array for use in sensing a first analyte and a second analyte, comprising:
a first microneedle comprising a first working electrode comprising a first biorecognition element configured to react with the first analyte, wherein the first biorecognition element is entrapped within a first biorecognition layer comprising a first conducting polymer, wherein a distal tip of the first microneedle is formed from a semiconducting material and comprises an insulating layer on the semiconducting material, and wherein a distal edge of the first working electrode is offset from the distal tip; and
a second microneedle comprising a second working electrode comprising a second biorecognition element configured to react with the second analyte, wherein the second biorecognition element is entrapped within a second biorecognition layer comprising a second conducting polymer, wherein a distal tip of the second microneedle is formed from a semiconducting material and comprises an insulating layer on the semiconducting material, and wherein a distal edge of the second working electrode is offset from the distal tip,
wherein the first analyte and the second analyte are different.
