This study introduces an allosteric palindromic hairpin probe (APHP)-based dual-mode interactive strand displacement amplification (DMI-SDA) system for ultrasensitive detection of microRNA-155. The system achieves exceptional signal amplification and improved signal preservation using dimeric G-triplexes as signal reporters, enabling robust detection of miRNA-155, representing a promising avenue in molecular diagnosis.
