<p>The present invention provides a method of detecting the presence of at least one target analyte (14) in a fluid sample (9), as well as linear array devices (5) of use in the method. In the method is provided a linear array device (5) comprising an elongate substrate (6) having a linear array of different spatially addressable probe moieties (7) anchored thereto. The device (5) is contacted with the sample under conditions conducive to selective binding with a probe moiety which I specific therefor. The device (5) is drawn past reading apparatus (3) for providing linear spatial address data for said probe moieties (7) and so as to detect signal indicating the presence of bound analyte (14), and the address data is correlated with bound analyte signal data so as to determine the linear spatial address of any probe moiety having analyte bound thereto, thereby to determine the identity of said probe moiety and thence indicate the presence or absence of target analyte (14).</p> |
