Figure 4: NIMS and SEM imaging using fluorinated AuNPs.
From: Comprehensive bioimaging with fluorinated nanoparticles using breathable liquids

(a) Mass spectra generated from two regions of interest in the f-AuNP MSI—one corresponds to the biofilm grown in balanced media (blue) and one corresponding to the biofilm grown in EAL media (red). The inset (b) shows the ion image for m/z 551. (c) SEM images of balanced and stressed biofilms treated with f-AuNP.
