Multiplex DNA detection.

Fluorescence intensity histograms of the probe mixture ([P_HIV] = [P_HBV] = [P_K167] = 50 nM) toward different target combinations in the presence of PMPD nanorods under excitation/emission wavelengths of 480/522, 587/601, and 643/660 nm/nm. All measurements were done in Tris-HCl buffer in the presence of 5 mM Mg²⁺ (pH: 7.4). 10-µL PMPD nanorods were used in each measurement.
