Fluorescent Aptasensor

A [Ru(bpy)2(bqdppz)]2+ ligand with high selectivity towards G-quadruplex was synthesized and introduced to serve as a prominent molecular light switch via specifically recognizing the cocaine aptamer-involved G-quadruplex.

Biophysical Techniques

The interaction of Ru1 with the triplex RNA poly(U)·poly(A)*poly(U) has been studied by various biophysical techniques. The results obtained here indicate that Ru1 may act as a sensitive luminescent probe for poly(U)·poly(A)*poly(U) in solution and can obviously stabilize the Hoogsteen base-paired third strand of the triplex.
