Illustration of in-vivo skin measurements by miniRaman MRs
a) Close view of miniRaman MRs, b) Screenshot of the miniRaman´s software during skin measurements and c) miniRaman MRs measurements using Android app
a) Raman spectrum of lipids and proteins in comparison with the spectrum of water, b) Skin measured using Skinmeter with and without background correction and averaging of 10 repetitions using laser at 785 nm and c) Skin measured using miniRaman MRs with and without background correction and averaging of 10 repetitions using laser at 660 nm.
Exposure time was 1s, laser power was 30mW for all presented spectra obtained from lasers with wavelengths 660nm and 785nm.
P-coumaric acid (pHCA) Raman spectra: green 0.5 g/L, red 0.25 g/L, purple 0.1 g/L and cyan 0 g/L.
Serine Raman spectra: green 50 g/L, purple 25 g/L, blue 10 g/L and red 0 g/L.
