Simultaneous detection of nucleic acid and protein targets using biotin—PEG—AuNP probes. (a) Detection of positive control molecules (PEG—biotin and biotinylated BSA); 3σ threshold = 315 au. (b) Detection of miRNA and positive control molecules (PEG—biotin and biotinylated BSA);, 3σ threshold = 216 au. (c) Detection of PSA protein and positive control molecules (PEG—biotin and biotinylated BSA); 3σ threshold = 105 au. (d) Simultaneous detection of miRNA, PSA, and positive control molecules (PEG—biotin and biotinylated BSA); 3σ threshold = 339 au.
