Identification of a biochemical marker for endothelial dysfunction using Raman spectroscopy

In the present work, we propose the spectroscopic approach to identify biochemical alterations in endothelial dysfunction. The method is based on the quantification of the ratio of phenylalanine (Phe) to tyrosine (Tyr) contents in the endothelium. The synthesis of Tyr from Phe requires the presence...
