It’s also important to note that the amide bending vibracharacteristic peaks elevated. It’s also vital to note that the amide bending vibration (ii and iii) for bioAgNPs disappeared, which may indicate that the bioAgNPs favored the tion (ii and iii) for bioAgNPs disappeared, which might indicate that the bioAgNPs Tunicamycin In Vivo fastrong intermolecular interaction with the CNC/Alg film.

The peaks generated around at 1594 cm-1 and 1410 cm-1 are characteristic in the asymmetric and symmetric elongation of carboxylate groups with the alginate polymer [51,57], thus suggesting the suc-Molecules 2021, 26,11 ofFigurecessful formation of ionic crosslinking in between the Ca+2 of the carboxylate group and the (-COO- ) of your alginate.
