FTIR analysis showed shifts and disappearance of peaks in fungal biomass treated with Ch-CuNPs, indicating molecular interactions and potential structural changes. This study underscores the potential of Ch-CuNPs as an effective antifungal agent and elucidates their interaction mechanisms....
Additionally, FT-IR showed the major chitosan peaks in the result of Chi-PLGA/Cer (Fig. 2b). Figure 2 FT-IR spectrum for confirmation of the composition of nanoparticles. (a) Standard materials comprising the PLGA nanoparticles, (b) PLGA nanoparticles according to the presence or absence ...
The structural analysis was carried out by XRD and FTIR analysis. The XRD patterns of the pure samples, chitosan, collagen, hydroxyapatite, and the different composites membranes are presented in Figs.1and2, respectively. The XRD pattern of chitosan membrane (Fig.1a) shows two principal peaks at...
The higher peaks shifted in films from malic acid in the 2000–1000 cm−1 range were due to the variations in the protonated amine concentration of the samples. The interaction between the solvent acid and chitosan increases as the pKa of the acid decreases. The pKa of malic and lactic ...
The FTIR spectrum of CCB in Fig. 1(a) indicates the presence of predominant peaks at 3379.8 cm−1 (–OH and –NH stretching), 2924.87 cm−1 (–CH stretching), 1661.0 cm−1 (–NH bending in –NH2), 1393.3 cm−1 (–NH deformation vibration in –NH2) and 1065.1 cm−1 (–...
