Using Raman spectroscopy for the evaluation of extracellular matrices based on heart valves

Not Accessible

Your library or personal account may give you access


Experimental data on the estimation of the qualitative composition of heart valves and their tissue bio-matrices via Raman scattering spectroscopy are presented. The analysis of the Raman spectra allowed identification of the main bands corresponding to collagen, glycosaminoglycans, lipids, and DNA. A two-dimensional analysis of the introduced optical coefficients was performed to compare the compositions of the principal components before and after sample preparation.
