(a) Three main light components within turbid media. (b) SERS spectra of
cabot nanoparticles (nP) with different labels. The Xs signify the identity peaks used to mea-
sure the nP flavor signal in the SESoRS spectrum. inset image is a 20 × 50 × 50 mm porcine
block with grid used to align injection points of nP. (Reproduced with permission from Ref.

2 mm. Left image shows all different signals plotted together with the injection points marked,
and right image shows the SERS signal of each labels. (Reproduced with permission from Ref.
[26]. © Royal Society of chemistry.) (
See insert for color representation of the figure.)
