Ag NPs@MXene-mediated electrochemical-SERS dual-mode microfluidic array for multiplexed breast cancer-associated miRNAs detection.
Breast cancer-associated miRNAs are promising liquid-biopsy biomarkers, but their low serum abundance, short sequences and matrix interference hinder sensitive and multiplexed detection. Herein, we developed an Ag NPs@MXene-mediated electrochemical-surface-enhanced Raman scattering (EC-SERS) dual-mode microfluidic arra...
