Patent ID: 8420025

Claim:
A system for simultaneously measuring a plurality of biological or chemical analytes in a fluid, said system comprising: a substrate comprising a plurality of sensor elements, each said sensor element responding to at least one of said plurality of analytes; at least one light source for directing light onto said sensor elements; a detector means for detecting a response from said sensor elements, wherein said detector means includes a processor that is programmed to: convert said response from each of said sensor elements into a digital record; execute an image identification algorithm for identifying said at least one analyte based on said digital record, wherein an analyte identification output is produced for each of said at least one analyte identified; and execute an optimization algorithm for identifying a concentration for each of said at least one analyte, wherein a concentration output is produced for each analyte identification output; and a delivery means for delivering metered quantities of said fluid to each said sensor element, wherein said delivery means comprises a delivery device comprising a plurality of reservoirs communicating with said sensor elements, said delivery device further comprising a sample entry port and a plurality of hydrophilic fluidic channels, said channels being connected between said reservoirs and said entry port so as to transport a controlled volume of said fluid between said entry port and said reservoirs, said delivery device further comprising a cover layer attached to said delivery device, said cover layer comprising a plurality of substantially hydrophobic vent holes disposed above said reservoirs, said cover layer further comprising a substantially hydrophilic bottom surface for providing a hydrophilic roof portion above said reservoirs to facilitate transport of said fluid to said reservoirs.
