Fluorescence images of aptamer control (A,B), 20-times diluted whole blood conjugates with residual insulin and HbA1c (C,D), MNP-QD-aptamer captured 50 pM insulin and 6% HbA1c (E,F), and 500 pM insulin and 10% HbA1c (G,H) in 20-times diluted whole blood upon binding to their respective surface immobilized antibodies on the SPR microarray chip. Scale bar: 20 μm for (A–H).
