Figure 3From: Surface modification of a polyhedral oligomeric silsesquioxane poly(carbonate-urea) urethane (POSS-PCU) nanocomposite polymer as a stent coating for enhanced capture of endothelial progenitor cells Detecting chemical groups via FTIR. FTIR spectra revealed that incorporation of NH2-FS did not alter the spectral read-outs. Amide I band was detected in anti-CD34 antibodies.Back to article page
