Schematic illustration of PNA-AuNP colorimetric detection assay. PNA immediately aggregates the AuNPs; however, hybridization of PNA with complementary RNA protects AuNP from aggregation, and the NPs remain stable. Non-complementary RNA did not hybridize with PNA; therefore, AuNP was aggregated in the presence of a charge-neutral PNA
