“…Characteristic peaks for chitosan can be determined on each spectrum without shifts, such as the peak at 3115 cm −1 from NH 2 and OH groups, at 1605 cm −1 from C=O and NH groups, at 1540 cm −1 from CN and NH groups, at 1372 cm −1 from CH 2 groups, at 1058 cm −1 and 1032 cm −1 from COH and CH 2 OH. A shift of peak from COC (1205 cm −1 for CTS_FA, 1208 cm −1 for CTS_GA, 1211 cm −1 for CTS_FA, 1290 cm −1 for CTS) can be noticed that suggests the changes in the conformation of chitosan after the addition of phenolic acids [ 15 ]. The spectra of each study’s scaffolds are analogous, as phenolic acids have similar functional groups, such as carboxyl and hydroxyl ones.…”

“…They showed good compatibility with NIH 3T3 L1 cells and the adhesion of fibroblasts was confirmed by SEM analysis [ 14 ]. Based on the obtained results, it was assumed that the proposed films were interesting for medical application due to their nontoxicity and antibacterial activity [ 15 ]. The last stage for the primary studies of chitosan-based materials modified by selected phenolic acids includes in vivo tests.…”

Chitosan-based scaffolds modified by gallic acid, ferulic acid, and tannic acid were fabricated. The aim of the experiment was to compare the compatibility of scaffolds based on chitosan with gallic acid, ferulic acid, or tannic acid using the in vivo method. For this purpose, materials were implanted into rabbits in the middle of the latissimus dorsi muscle length. A scaffold based on unmodified chitosan was implanted by the same method as a control. Moreover, the Fourier transform infrared spectroscopy-attenuated total reflectance (FTIR-ATR) spectra and scanning electron microscope (SEM) observations were made to study the interactions between chitosan and phenolic acids. Additionally, antioxidant properties and blood compatibility were investigated. The results showed that all studied materials were safe and non-toxic. However, chitosan scaffolds modified by gallic acid and tannic acid were resorbed faster and, as a result, tissues were organized faster than those modified by ferulic acid or unmodified.

“…Examples of industrial test methods to determine degradability include biodegradation tests (ISO 14855) and disintegration tests (ISO 16929), with a maximum testing duration of 180 days within a specified temperature range. “Biodegradable” polymers have a primary degradation mechanism based on microorganism-related metabolism . Pristine chitosan has a good biodegradation capacity, which may be enhanced using ubiquitous hydrolase enzymes .…”

We report a novel cross-linked chitosan composite film containing vanillin, glycerol, and green tea extract. The effects of vanillin-mediated cross-linking and the incorporation of antimicrobial green tea polyphenols were investigated. The cross-linking effect, confirmed by Fourier transform infrared (FTIR) analysis, increased the tensile strength of the biopolymer film to 20.9 ± 3 MPa. The release kinetics of polyphenols from the chitosan–vanillin matrix was studied, and we reported an initial burst release (8 h) followed by controlled release (8 to 400 h). It was found that both vanillin and green tea polyphenols were successful inhibitors of foodborne bacteria, with a minimum inhibitory concentration of the tea polyphenols determined as 0.15 mg/mL (Staphylococcus aureus). These active components also displayed strong antioxidant capacities, with polyphenols quenching >80% of 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals at all concentrations tested. Degradation results revealed that there was a significant (>85%) mass loss of all samples after being buried in compost for 12 weeks. The biopolymeric films, prepared by solvent casting methods, adhere to green chemistry and waste valorization principles. The one-pot recipe reported may also be applied to other cross-linkers and active compounds with similar chemical functionalities. Based on the obtained results, the presented material provides a promising starting point for the development of a degradable active packaging material.

Chitosan-based scaffolds modified by gallic acid, ferulic acid, and tannic acid were fabricated. The aim of the experiment was to study the compatibility of scaffolds by in vivo method. For such purpose materials were implanted into rabbit in the middle of the latissimus dorsi muscle length. Scaffold based on unmodified chitosan was implanted by the same method as a control. The results showed that all studied materials were safe and nontoxic. However, chitosan scaffolds modified by gallic acid and tannic acid were resorbed faster and as a result tissues were organized faster than those modified by ferulic acid or unmodified.
