(A); Schematic picture of dual amplification strategy based on isothermal exponential amplification reaction (EXPAR) coupled with hybridization chain reaction (HCR) of DNAzymes nanowires for electrochemical genosensor technique. (B); Conjugation of plasmonic NPs with l-glutathione-capped CdSeS alloyed Qdots makes NP-Qdots hybrids that further conjugate to MB. Finally, an LSRP-mediated fluorescent signal is detected as a result of the hybridization of target RNA and MB. The figures are obtained from ref [214,225].
