“…[48][49][50][51] Coincidently, recent studies have shown that PVP has great water solubility, low toxicity, biocompatibility, and exhibits promising results against antimicrobial activity. [52][53][54][55] Chitosan is an alkaline polymer prepared by partially hydrolyzing chitin, the primary component of crustaceans and fungus cells, and extensively used for pharmaceutical and biomedical purposes. It has superior biodegradability, biocompatibility, low toxicity, and lm-forming characteristics.…”

The current work examined chitosan's adsorption capabilities for removing Cu(II) and Fe(II) ions from the aqueous phase in a batch equilibrium system. The membranes were prepared using the leaching-out method. The effects of the adsorbent's initial pH, concentration, temperature, and dose on adsorption were examined. Adsorption tests were conducted at temperatures ranging from 15 to 45 °C and initial concentration ranges of 20−400 mg/L. The observations from the adsorption isotherms fitted the Langmuir and Freundlich model adequately. The nonlinear form of the pseudo-first-order model was followed by the kinetics of Cu(II) and Fe(II) on chitosan, and the model parameters were reliably obtained. The endothermic and spontaneous character of Cu(II) and Fe(II) adsorption on chitosan adsorbents was verified by the computed negative values of standard Gibbs free energy and positive enthalpy changes. Finally, chitosan (CS) showed to be an efficient adsorbent for the removal of Cu(II) and Fe(II) ions due to its high adsorption capacity for Cu(II), which was 182.15 mg/g for C1, 331.28 mg/g for C2, and 384.31 mg/g for C3, and Fe(II), which was 201.67 mg/g for C1, 352.53 mg/g for C2, and 315.8 mg/g for C3 (where C1 is the CS membrane, C2 is the CS/silica membrane, and C3 is the CS/polyvinylpyrrolidone membrane).

“…Thus, nanosheet-containing films can be easily fabricated via solvent-casting method . Mogbel et al incorporated graphene oxide (GO) nanosheets into polyvinylpyrrolidone (PVP)/chitosan films to improve the antibacterial activity of films . However, graphene nanosheets are cytotoxic and bioincompatible. , Therefore, there is a need for a novel alternative to graphene nanosheets that is biocompatible and noncytotoxic.…”

Wound healing using an alginate-based biopolymeric film is one of the most preferred treatments. However, these films lack mechanical strength (elasticity and tensile strength), show higher initial burst release, and exhibit high vapor permeability. The present study reports the development of nanosheets derived from titanium diboride (10 nm) (NTB)-incorporated biopolymeric films (0.025, 0.05, and 0.1% w/v) using sodium alginate (SA) and carboxymethyl cellulose (CMC) to overcome the shortfalls. The surface properties of the film, nanosheet distribution within the film, and possible interactions with the film are explored by using scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), Fourier transform infrared (FTIR), and X-ray diffraction (XRD). These analyses confirm that nanosheets are uniformly distributed in the film and introduce unevenness on the film's surface. The tensile strength of the nanosheet-incorporated film (0.1% NTB film) using UTM is found to be 24.30 MPa (six times higher compared to the blank film), equivalent to human skin. The water vapor transmission rate of the film is also found to be in the desired range (i.e., 2000−2500 g/m 2 day). The biocompatibility of the NTB film is confirmed by the MTT assay test using NIH/3T3 cells and HEK 293 cells. Furthermore, the scratch assay shows that the developed films promote cell migration and proliferation. The antibacterial activity of the film is also demonstrated using a model drug, tetracycline hydrochloride (TCl). Besides, the film exhibits the sustained release of TCl and follows the Korsmeyer−Peppas model for drug release. Overall, the 0.1% w/v NTB film is easy to fabricate, biocompatible and shows superior mechanical properties.
