Figure Lengend Snippet: Mixed sample detection results. (a) Higher concentration of Aβ42 biomarker vs. lower concentration of hsa-miR-125b biomarker. The absolute concentrations were (Aβ42 : 125b): 10 pM : 1 fM (10 000 : 1); 50 nM : 50 pM (1000 : 1); and 100 nM : 1 nM (100 : 1). (b) Higher concentration of hsa-miR-125b biomarker vs. lower concentration of Aβ42 biomarker. The absolute concentrations were (125b : Aβ42): 100 nM : 1 fM (10 8 : 1), 100 nM : 1 pM (10 6 : 1), and 50 nM : 50 pM (10 3 : 1). (c) Fixed concentration of Aβ40 biomarker and varying concentrations of hsa-miR-125b ( n ≥ 13, n is number of sensors used for each measurement).
