Abstract The technology for sequence-specific detection of RNA is in high demand in the medical field as well as in basic research in life sciences. Various methods for detecting RNA have been developed so far, but all of them are designed based solely on the rules of base complementarity, which leads to the false detection of unrelated RNAs with very similar sequences. In this study, we challenged the biomimetics approach at the molecular level to develop a sequence-specific RNA probe by mimicking a well-known RN…
