Fig. 5From: Dancing in local space: rolling hoop orbital amplification combined with local cascade nanozyme catalytic system to achieve ultra-sensitive detection of exosomal miRNAAnalysis of clinical sample detection results. A Schematic drawing of the clinical sample testing process. B Correlation analysis between the detection results of ECL biosensor and qRT-PCR. C, D Are the detection results of miRNA-15a-5p in serum exosomes (S1–S4) of clinical endometrial cancer patients detected by the ECL biosensor and qRT-PCR, respectively.
