Fig. 5From: Impact of seed amplification assay and surface-enhanced Raman spectroscopy combined approach on the clinical diagnosis of Alzheimer’s diseaset-SNE plot obtained by applying t-SNE algorithm to SERS spectra of SAA products of CSF samples. Circles in red-yellow-green color scale refer to SERS spectra acquired from AD patients, while blue-violet diamonds point out to ONC patients. Same colored group symbol refers to the same patient labeled by a number following the list in Table 1Back to article page
