Abstract

A composition comprising an oligonucleotide having the structure 5′-Y1-L1-X-L2-Y2-3′. Y1 comprises a sequence of one or more DNA or RNA nucleotides, including a first nucleotide N1 having a 3′ phosphate covalently linked to L1. Y2 comprises a sequence of one or more DNA or RNA nucleotides, including a second nucleotide N2 having a 5′ phosphate covalently linked to L2. L1 and L2 each independently are a direct bond or a C1-C7 alkyl, alkynyl, alkenyl, heteroalkyl, substituted alkyl, aryl, heteroaryl, substituted aryl, cycloalkyl, alkylaryl, or alkoxyl group. X isR1 is a hydrogen or a C1-C8 alkyl. M is a label or ligand comprising a fused polycyclic aromatic moiety.
