Abstract The oil/water (o/w) separation is a global challenge because of the increasing water contamination by oil spill accidents, and oil-containing wastewater produced by food, textile, and petrochemical industries. In this study, we have developed bacterial cellulose (BC) based superhydrophilic/underwater superoleophobic (SUS) membrane for o/w separation. The membrane was designed through a facile method by blending BC nanofibers with silica microparticles (SiO2-MPs), which was further modif...

Abstract Bacterial cellulose (BC) is a substrate material with high purity and robust mechanical strength, but due to its small pore size and relatively expensive price, it is restricted as an oil-water separation membrane. In this study, cheaper plant cellulose needle-leaf bleached kraft pulp (NBKP) was added to BC to increase the pore size of the composite membrane, and a superhydrophobic/superoleophilic membrane was prepared for oil-water separation. The modified membrane surface displayed a ...

Abstract Hydrogels mimic the tissue environment because of their hydrophilic and porous network structures. They are widely investigated in biomedical and biotechnological fields, however, due to the poor mechanical properties and limited functions, their further applications are restricted. In order to tackle these problems, an emerging approach is focused on the development of nanocomposite hydrogels. Numerous nanoparticles, including carbon-based, silica, polymeric, and metal-based nanopartic...

Abstract Bacterial infections are currently a major concern to human health. Amino acid-based supramolecular polymer hydrogels, which boast intrinsic antibacterial activity, are an important solution due to their good biocompatibility, cost effectiveness, and tunable structural properties. Herein, we reported three types of transparent supramolecular hydrogel with intrinsic antibacterial activity from self-assembly of commercially available Fmoc-tryptophan (Fmoc-W), Fmoc-methionine (Fmoc-M), and...

Large-scale production of an antibacterial hydrogel is of critical importance for its practical application in biomedical field. In this regard, herein we report on the construction of a double-syringe injection device by using all the commercial parts and its use for continuous production of carboxymethyl chitosan-zinc (CMCh-Zn) supramolecular hydrogel fiber. The resultant CMCh-Zn hydrogel fibers exhibit good stretchability and knittability. The Zn loading into the hydrogel fibers can be easily...

Abstract The absence of antibacterial activity in bacterial cellulose (BC) restricts its applications in the biomedical field. To introduce antimicrobial properties into BC, we studied the synthesis, structures, and antimicrobial properties of a novel nanocomposite film comprising BC, graphene oxide (GO), and copper-oxide (CuO) nanosheets. The nanocomposite film was synthesized by incorporating GO-CuO nanohybrids into BC matrix through homogenized blending. The CuO nanosheets, with a length rang...

Bacterial cellulose (BC) has numerous unique properties; however, the lack of antibacterial properties has restricted its biomedical applications. To resolve this problem, we have developed BC/polyethyleneimine (PEI)-based antibacterial hydrogels by a facile two-step-one-pot method using epichlorohydrin (ECH) as a coupling agent. ECH was added to BC solution and homogenized, followed by cross-linking with different content of PEI. The prepared hydrogels showed thermal stability, moldability, and...

Abstract The combination of high mechanical properties, antibacterial activity and a green synthesis of the polyvinyl alcohol (PVA) based films remains challenging. This study presents a ternary system of PVA films containing bacterial cellulose (BC) and epsilon-polylysine (e-PL) by a green solution casting method. The prepared composite films showed more than 99% antibacterial properties against both Staphylococcus aureus and Escherichia coli bacteria. Moreover, the films were collected after a...

Abstract Bacterial cellulose (BC) has numerous excellent properties but the absence of antibacterial activity restricts its applications in biomedical field. Therefore, in order to introduce the antibacterial characteristics into BC; herein, a facile method for incorporation of ZnO nanoparticles (ZnO-NPs) is presented. BC films were first immersed in zinc nitrate solution, followed by treating with NaOH solution, the BC loaded ZnO nanocomposite films were dried by a sheet former instrument at 80...
