Physico-Mechanical Optimization and Antimicrobial Properties of the Bionanocomposite Films Containing Gallic Acid and Zinc Oxide Nanoparticles.

ABSTRACT: The mechanical and physical properties of the bionanocomposite films based on κ-carrageenan (KC)-gelatin (Ge) containing zinc oxide nanoparticles (ZnONPs) and gallic acid (GA) were optimized using the response surface method, and the optimum amounts of 11.19 wt% GA and 1.20 wt% ZnONPs were obtained. The results of XRD, SEM, and FT-IR tests showed the uniform distribution of the ZnONPs and GA in the film microstructure, and suitable interactions between biopolymers and these additives, which led to increasing the structural cohesion of the biopolymer matrix and improving the physical and mechanical properties of the KC-Ge-based bionanocomposite. In the films containing gallic acid and ZnONPs, an antimicrobial effect was not observed against E. coli; however, the GA-loaded and optimum films show an antimicrobial effect against S. aureus. The optimum film showed a higher inhibition effect against S. aureus compared to the ampicillin- and gentamicin-loaded discs.

Project description:The goal of this research was to analyse the synergistic effect between selected plant extracts with zinc oxide particles, and zinc stearate. The influence of ZnO on the antimicrobial effectiveness of the selected extracts was confirmed in previous research carried out by the authors. However, the impact of zinc stearate on extract activity has yet to be analysed. The aim was to cover PLA films with active coatings based on hydroxy-propyl-methyl-cellulose (HPMC), or/and ethyl cellulose (EC) containing plant extracts and ZnO which has a synergistic effect. An additional aim was to use a CO2 extract of raspberry seed (RSE) with zinc stearate as active additives within the coatings. An examination of the antimicrobial properties (against Staphylococcus aureus, Escherichia coli, Bacillus subtilis, Pseudomonas syringae and Φ6 bacteriophage) of the covered films, as well as an investigation of layer presence with regards to PLA morphology (SEM, ATR-FTIR analysis) was carried out. The research work that was performed indicated that black chokeberry extract (ChE) and zinc oxide particles were effective against S. aureus, P. syringae and B. subtilis strains. In addition, the ChE with zinc stearate (ZnSt) was active against all analysed strains. The HPMC with ChE and ZnO as additives had antimicrobial properties against S. aureus, P. syringae and E. coli strains. The ChE was found to inhibit the growth of all of the analysed bacterial strains. When considering the coatings based on EC with the CO2 extract of raspberry seed (RSE) and ZnO, it was noted that they were only active against Gram-negative bacteria. The results of the experiments confirmed that AC1 (EC with RSE with ZnO) and AC2 (EC with RSE with ZnSt) coatings were not active against a phi6 bacteriophage. The HPMC coating containing the AC3 layer (ChE and ZnO) eliminated Φ6 particles, confirming its antiviral properties. In addition, the presence of the active (AC1, AC2 and AC3) coatings was confirmed by SEM and FTIR analysis.

Project description:In this study, developing mucoadhesive oral films with optimized olive leaf extract (OLE) and microencapsulated thyme essential oil (TEO) contents was aimed to create a novel oral delivery system with desirable film properties as well as enhanced bioactivities. For this, TEO-containing sodium alginate/okra gum microcapsules were first fabricated at optimized electrospray conditions, where optimization was performed for three parameters, which are the flow rate of the emulsion solution, the potential difference, and the distance between the nozzle of the sample container and the collector plate, through three-level centered Box-Behnken design. Prior to the inclusion of the OLE in custom-designed mucoadhesive films, polymeric components of the films were also optimized through a separate multi-variable, three-level Box-Behnken experimental design by which the effect of mixing ratios of Carbopol 934, hydroxypropyl methylcellulose and polyethylene glycol on viscosity, solution pH, film pH, disintegration time, thickness, and weight were elaboratively investigated. The resulting films, containing OLE and microencapsulated TEO, obtained through solvent casting were characterized for pH, viscosity, mass uniformity and thickness, dispersion, tensile strength, folding endurance, contact angle, in vitro mucoadhesion time, and ex vivo mucoadhesion force. Results showed that the film had good tensile strength, swelling capacity, compatibility with oral mucosa, and flexibility. It also demonstrated desirable stability and adhesion ability. Regarding bioactivity, the film was found to have desirable antioxidant capacity and it was non-toxic to fibroblast cells when diluted to certain concentration. Moreover, antiviral studies indicated reductions of 32.39% and 54.29% against Poliovirus Type 1 and Murine Norovirus, respectively, while preliminary antibacterial tests showed no significant reduction in certain bacteria within 1 min, but a logarithmic reduction in Staphylococcus aureus was observed. Despite favorable mucoadhesion properties and physical attributes, further investigation is needed to enhance the antimicrobial effectiveness of the films for their potential utilization in drug delivery systems.
