ABSTRACT
Structural RNA is a challenging target for recognition by hybridization probes. This chapter addresses the recognition problem of RNA amplicons in samples obtained by multiplex nucleic acid sequence-based amplification (NASBA). The method describes the design of G-quadruplex binary (split) DNA peroxidase sensors that produces colorimetric signal upon recognition of NASBA amplicons.

ABSTRACT
Visual detection of ssRNA and dsDNA amplicons was achieved at room temperature without the need for a probe-analyte annealing stage. This approach uses a DNA nanostructure equipped with two analyte-binding arms. Highly selective binding of the third arm leads to the formation of a G-quadruplex structure capable of changing the solution color.
