Infrared spectra of a) TPP b) Collagen beads treated with 0.245 M TPP and after competitive desorption with 250 mM NaCl for different time periods. As the desorption time increased from 10 min to 96 h, there is a gradual decrease in the TPP-associated peaks. After 120 h, the spectrum (not shown) is similar to that of untreated collagen.
