A Dual-Mode Fluorescent and Colorimetric Biosensor Based on AuNPs@RCA Nanogel-Integrated Multipedal DNA Walker for Ultrasensitive miRNA Detection.
A dual-mode fluorescence-colorimetric biosensing platform for the ultrasensitive detection of miRNA-21, integrating AuNP-supported dual-stage rolling circle amplification (RCA) with an RCA-generated multipedal binding-and-cleavage mechanism, demonstrating excellent specificity and distinguished the endogenous responses...
