Figure 5. DNA nanoswitch barcodes for prostate cancer biomarker panel.

Figure 5.

(a) An illustration of the three chosen prostate cancer biomarkers (miR-141, miR-30c and PSA). (b) DNA nanoswitch mixture for detecting prostate cancer biomarker panel. (c) Barcode detection of individual biomarkers (DNA analogs of microRNAs 141 and 30c, and PSA) and simultaneous detection of all three biomarkers in buffer and 20% fetal bovine serum (FBS).
