“…Wang Smart textiles incorporating green nanomaterials can be used for air filtration. For example, nanocellulose fibres have high filtration efficiency and low pressure drop, making them a practical and energy-efficient option for air filtration [187][188][189][190][191]. Jhinjer et al [192] developed an in situ growth of zeolitic imidazolate metal-organic framework (ZIF MOF) on carboxymethylated cotton fabric for the adsorption of organic pollutants (aniline, benzene, and styrene).…”

GO-Enabled Bacterial Cellulose Membranes by Multistep, In Situ Loading: Effect of Bacterial Strain and Loading Pattern on Nanocomposite Properties

This paper presents the results of research on the preparation and properties of GO/BC nanocomposite from bacterial cellulose (BC) modified with graphene oxide (GO) using the in situ method. Two bacterial strains were used for the biosynthesis of the BC: Komagataeibacter intermedius LMG 18909 and Komagataeibacter sucrofermentans LMG 18788. A simple biosynthesis method was developed, where GO water dispersion was added to reinforced acetic acid-ethanol (RAE) medium at concentrations of 10 ppm, 25 ppm, and 50 ppm at 24 h and 48 h intervals. As a result, a GO/BC nanocomposite membrane was obtained, characterized by tensile strength greater by 150% as compared with the pure BC (̴ 50 MPa) and lower volume resistivity of ~4 ∙ 109 Ω × cm. Moreover, GO addition increases membrane thickness up to ~10% and affects higher mass production, especially with low GO concentration. All of this may indicate the possibility of using GO/BC membranes in fuel cell applications.

“…Earlier studies have demonstrated that the surface of BC can be improved for various applications through the use of different types of plasmas. The application of nitrogen plasma for BC modification has been found to improve the adhesion of eukaryotic cells to the BC surface and increase its porosity [10,11]. The modification of BC membranes' surfaces using oxygen plasma can lead to a decrease in the effective pore area and water flux, while increasing the number of O-H groups.…”

“…As a result, there is a significant change in the water contact angle, making the membrane surface more hydrophilic [12]. The modification of BC with argon plasma can confer bactericidal properties, making it suitable for use as antibacterial and antiviral filters based on BC [11]. Moreover, the introduction of new functional groups on the surfaces of polymer matrices through plasma exposure may affect the release process of active compounds, including enzymes, from the surfaces of polymeric materials, especially in applications related to biofilm eradication [13][14][15][16].…”

Bacterial cellulose is a unique biopolymer that has found numerous biomedical applications, such as being an excellent wound-dressing material or a carrier for delivering active compounds. The purpose of this study was to analyze the ability of modified bacterial cellulose (BC) using low-pressure Ar plasma to control the release of glycoside hydrolases with antibiofilm activity, namely PelAh and PslGh, from Pseudomonas aeruginosa. The chemical composition and morphology of the BC surfaces were characterized using photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). The analyses revealed significant changes in the chemical composition of the BC surface due to the introduction of charged functional groups and the conversion of its well-ordered structure into a more amorphous form. The release profiles of enzymes from both forms of the carrier were different and depended on their structural properties. However, a significant impact of BC modification on protein release behavior from the carrier was observed only for PslGh. Both enzymes, when immobilized on pristine and argon plasma-modified BC, retained their ability to effectively reduce biofilm levels, similarly to their soluble form. Ar plasma-modified BC with immobilized specific hydrolases can be used as an effective tool for inhibiting P. aeruginosa biofilm development.
