Abstract:
1. 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: 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.
