1. A process for detecting or quantifying non-nucleic acid analytes of interest, said process comprising the steps of:

  • 1) providinga) an array on a solid surface comprising a plurality of discrete areas;

    whereinat least two of said discrete areas each comprise a nucleotide sequence fixed or immobilized to said discrete areas,said at least two discrete areas comprise a first discrete area and a second discrete area, andsaid nucleotide sequence on said first discrete area is different from said nucleotide sequence on said second discrete area;

    b) chimeric compositions consisting of;

    i) a nucleic acid portion; and

    ii) a non-nucleic acid portion;

    whereinsaid nucleic acid portion of each chimeric composition is complementary to a nucleotide sequence of said array,said nucleic acid portion of the chimeric composition that is complementary to the nucleotide sequence located at said first discrete area has a different sequence from that of said nucleic acid portion of the chimeric composition complementary to the nucleotide sequence located at said second discrete area,said non-nucleic acid portion of the chimeric composition that has a nucleic acid portion that is complementary to the nucleotide sequence of said first discrete area has a binding affinity for a first non-nucleic acid analyte of interest and said non-nucleic acid portion of the chimeric composition that has a nucleic acid portion that is complementary to the nucleotide sequence of said second discrete area has a binding affinity for a second non-nucleic acid analyte of interest,said first non-nucleic acid analyte is different from said second non nucleic acid analyte,when said non-nucleic acid portion of a chimeric composition is a peptide or protein, said nucleic acid portion of said chimeric composition does not comprise a sequence which is either identical or complementary to a sequence that codes for said peptide or protein, andsaid nucleic acid portion i) and said non-nucleic acid portion ii) are covalently attached to each other;

    c) a sample containing or suspected of containing said non-nucleic acid analytes of interest, whereinsaid non-nucleic acid analytes of interest comprise oligopeptides, polypeptides, oligosaccharides, polysaccharides, lipids, ligands, or combinations thereof; and

    d) signal generating means;

    2) contacting said array with said chimeric compositions to hybridize the nucleic acid portions of said chimeric compositions to complementary nucleotide sequences fixed or immobilized to said array;

    3) contacting said array with the sample under conditions permissive of binding said non-nucleic acid analytes to said non-nucleic acid portion;

    4) contacting said bound non-nucleic acid analytes with said signal generating means; and

    5) detecting or quantifying the presence of said non-nucleic acid analytes by measuring said signal generating means bound to said array.
