Use of Non-nucleophilic Additives for Reduction of Surface Morphological Anomalies in Probe Arrays

The present invention relates to a formulations and methods for coupling a reactant (or probe precursor) to a functionalized surface for purposes of forming an arrayed sensor. This method includes the steps of: providing a surface having a reactive functional group; and introducing onto the surface, at a plurality of discrete locations, two or more compositions of the invention, which include a different reactant (probe precursor) and a non-nucleophilic additive, wherein such introduction is carried out under conditions effective to allow for covalent binding of the reactant to the surface via the reactive functional group. This results in a probe-functionalized array that substantially overcomes the problem of surface morphological anomalies on the array surface. Use of the resulting arrays in various detection systems is also encompassed.
