Abstract
We here present a novel mobile instrument based on shifted excitation Raman difference spectroscopy (SERDS) in combination with resonance Raman spectroscopy with the aim to analyze physiologically relevant carotenoid concentrations in human skin. Interferences from skin autofluorescence and ambient light are effectively addressed by our approach. We apply SERDS using an in-house developed micro-integrated 488 nm dual-wavelength diode laser system as excitation light source. Initial measurements on skin phantoms demonstrate the capability for quantitative carotenoid assessment with limits of detection of 0.05 nmol/g. Preliminary clinical data confirm that the SERDS system is highly effective for in vivo skin carotenoid assessment, making it a promising tool for non-invasive antioxidant monitoring.
