A device is described for use in an oligonucleotide assay having predetermined portions of its surface treated for covalent binding. The device comprises: a) a receptor material disposed upon and covalently bound to the treated predetermined portions, the receptor material partially covering the treated portions and leaving uncovered interstices therebetween of the surface treated for covalent binding; and, b) masking means for masking the uncovered interstices of surface treated for covalent binding, the masking means substantially covering and bound to the uncovered interstices without interfering with the receptor material. |
