A structure and method for chemical sensing utilizing microassays. Microcavities
or micropores are combined with assay techniques to provide a very fast and very
sensitive means of detecting chemical compounds. Assay techniques are modified
to include a metal ion binding carrier species especially suitable for use in conjunction
with the electrochemical detection. This allows assays to be combined with electrochemical
analysis, thus allowing the high speed ease and hypersensitivity available in the
invention disclosed herein.
