Figure 5: Detection of virus in pooled human saliva on a flexible substrate.

Figure 5:

(A) Scheme of the experiment. Inset shows a photographic image of the flexible substrate with the nanostructures at the center. (B) Raman spectra of the saliva spiked with SARS-CoV-2 containing cell lysate and the control acquired on FEMIA on a flexible substrate. The spectra are vertically offset for easier visualization. (C) Classification accuracy using binary random forest classification for the saliva samples. The black box represents the median value. (D) ROC curve for the performance of the model.
