ABSTRACT:
A sensor device for the analysis of a sample fluid comprises a substrate in a surface of which an elongate channel is micromachined. The channel contains a material, such as a starch, agarose, alginate, carrageenin or polyacrylic polymer gel, with a biological material for causing separation of the sample fluid as the fluid passes along the channel. The biological material may comprise, for example, a binding protein, an antibody, a lectin, an enzyme, a sequence of enzymes or a lipid. Pairs of sensing electrodes are spaced apart along the walls of the channel. The device may be used, for example, for testing blood samples.
