Table 3:

Pentosidine (PEN) SERS-peak locations compared to previously reported PEN peaks in the literature along with the SERS-peak locations of glucosepane (GLU) and bone specimen. * reported peaks with tilde (~) in the table were read directly from the corresponding figures, these peaks were not reported in those papers.
