1. An implantable microarray device comprising:
- an inlet for a body fluid;
one or more splitter channels coupled to the inlet, the splitter channels being adapted to divide the body fluid into smaller volumes;
a plurality of individual reaction cell arrays coupled to the one or more splitter channels, wherein each reaction cell array comprises a series of reaction cells configured to receive the body fluid;
a sensor array to sense a reaction result for an individual reaction cell array wherein the reaction result corresponds to a reaction between the body fluid and at least one reagent in each of the reaction cells of the individual reaction cell array; and
a positioning mechanism to position an individual reaction cell array with respect to the sensor array.
