MALDI-TOF mass spectra of four simulated co-infection clinical samples. (a): The mass spectrum of sample No.1, indicating it is positive for DRV-1 and DRV-2; (b): The mass spectrum of sample No.2, indicating it is positive for DHAV-1, DHAV-3, DAstV-1, and DAst-2; (c): The mass spectrum of sample No.3, indicating it is positive for AIV, DRV-1, DEV, and GPV; (d): The mass spectrum of sample No.4, indicating it is positive for DHAV-1, DHAV-3, DAstV-1, DAstV-2, DRV-1, DRV-2, TMUV, AIV, GPV, and DEV. The x-axis (m/z) represents the mass (Daltons) of extension primer and the y-axis represents the intensity (Volts). The red arrow indicates the positive target.
