The Vespucci main window and file import dialog. Vespucci uses the user’s native file dialog to select the file for import. Metadata can be specified by the user.
Figure 2
The Vespucci dialog used to perform smoothing.
Figure 3
The Vespucci dialog used to perform normalization by peak intensity.
Figure 4
The Vespucci dialog for performing CWT peak detection. Vespucci includes the first implementation of the CWT peak detection algorithm with a graphical user interface.
Figure 5
The “chemical barcode” produced by applying the peak finding method to all spectra in the dataset.
Figure 6
Using Vespucci to examine the spatial distribution of SERS hotspots. The colour scale corresponds to the Riemann sum of the xanthine breathing-mode peak. Spots higher on the colour scale (e.g., white or red) indicate better surface-enhancement capability.
Figure 7
A comparison of the surface-enhancing capabilities of two AgNR synthesis methods in Vespucci. The image on the left is from an AgNR SERS substrate synthesized in cryogenic conditions. On the right, an AgNR substrate synthesized in ambient conditions. The colour scale is mapped to the Riemann sum of the spectral region from 1625 to 1675 cm–1. The presence of more white-coloured spots in the right spectral map indicates an overall improvement in enhancement compared to the left spectral map.

Figure 9
A crystal found in a chick embryo tibiotarsus. A and C depict the colour and greyscale representations of a divergent “rainbow” colour scheme. B and D depict the colour and greyscale representations of a colour scheme that increases linearly in perceived brightness.
