“…NFs are one-dimensional nanomaterials whose properties make them suitable for a wide range of applications, including drug delivery [ 40 , 41 ], tissue engineering [ 42 ], water/air filtration [ 43 ], energy storage [ 44 ], protective clothing [ 45 ], sensors or photocatalytics [ 46 ], among others [ 47 , 48 ]. One of the key features of NFs is their large surface area to volume ratio, which allows them to interact with their surroundings in ways that are not possible with larger fibers [ 49 ]. This can make them more effective at adsorbing or filtering small molecules or particles [ 50 ].…”

Phytochemical-Based Nanomaterials against Antibiotic-Resistant Bacteria: An Updated Review

et al. 2023

Antibiotic-resistant bacteria (ARB) is a growing global health threat, leading to the search for alternative strategies to combat bacterial infections. Phytochemicals, which are naturally occurring compounds found in plants, have shown potential as antimicrobial agents; however, therapy with these agents has certain limitations. The use of nanotechnology combined with antibacterial phytochemicals could help achieve greater antibacterial capacity against ARB by providing improved mechanical, physicochemical, biopharmaceutical, bioavailability, morphological or release properties. This review aims to provide an updated overview of the current state of research on the use of phytochemical-based nanomaterials for the treatment against ARB, with a special focus on polymeric nanofibers and nanoparticles. The review discusses the various types of phytochemicals that have been incorporated into different nanomaterials, the methods used to synthesize these materials, and the results of studies evaluating their antimicrobial activity. The challenges and limitations of using phytochemical-based nanomaterials, as well as future directions for research in this field, are also considered here. Overall, this review highlights the potential of phytochemical-based nanomaterials as a promising strategy for the treatment against ARB, but also stresses the need for further studies to fully understand their mechanisms of action and optimize their use in clinical settings.

Experimental study and modelling of an azo colourant dynamic adsorption onto functional cross‐linked chitosan/ceramic particles in a fixed bed column

The use of azo dyes in industrial activities generates a large volume of contaminated wastewater; these pollutants in water bodies affect aquatic biota and human health. A functional biocomposite sorbent material was synthesized using cross‐linked chitosan with oxalic acid that forms a coating on alumina ceramic particles (AOCh). The removal of Reactive Red 195, a reactive azo dye, using a fixed‐bed adsorption column filled with this material was tested. AOCh was physico‐chemically characterized by Fourier transform infrared spectroscopy–total attenuated reflection (FTIR‐ATR), scanning electron microscopy–energy dispersion spectrometry X‐ray (SEM‐EDS), X‐ray diffraction (XDR), thermo‐gravimetric analysis (TGA), and Z‐potential. The dynamic adsorption performance was analyzed from experimental breakthrough curves obtained in fixed‐bed columns by modifying different operating conditions (bed depth, volumetric flow rate, and dye inlet concentration). Equilibrium adsorption isotherms were determined under dynamic conditions and compared with batch results. The maximum adsorption capacity of the dynamic equilibrium isotherm obtained from the continuous assays was 331 mg/g; this value was the highest in comparison to other tested materials reported in the literature. Different dynamic adsorption models were applied to fit experimental data, including Thomas, Bohart–Admas, Yoon–Nelson, logistic general model, bed depth surface time (BDST), and modified dose response (Yan) models. A critical analysis of these equations was presented, showing the equivalences and the relationship among the coefficients. The Yan model achieved the highest level of agreement between the experimental and predicted values of the breakthrough curves. The use of this model enables scaling‐up the industrial process for dye removal. The present work proposed a novel biosorbent material and contributes to the analysis of industrial dye removal under dynamic conditions.

“…Nonetheless, the stiffness and strength presented by NFC-E50 are suited for applications in food packaging, with values comparable to those displayed by the most frequently used packaging polymers (Vimala Bharathi et al, 2020) and well above those of green composite films, such as starch (Sethi et al, 2019a), chitosan (Soni, Hassan, Schilling, & Mahmoud, 2016) and PCL (Gutiérrez et al, 2020). The plot shows that transport of water vapor through the thickness is considerably reduced as BW content in composites film increases, given the presence of a thin hydrophobic layer responsible for avoiding adsorption and hindering the interfiber and interpore diffusion.…”

“…Natural waxes like carnauba and beeswax (BW) appear as suitable alternatives to promote hydrophobization of biobased films (Morrissette et al, 2018;Tedeschi, Benitez, et al, 2018;Vimala Bharathi, Murugesan, Moses, & Anandharamakrishnan, 2020). BW is a natural material of complex structure and has been considered as a barrier layer for paper packaging since the 1990s by Fennema and co-workers (Donhowe & Fennema, 1993;Fennema, Donhowe, & Kester, 1994;GONTARD, DUCHEZ, CUQ, & GUILBERT, 1994;KESTER & FENNEMA, 1989).…”
