Despite the widely explored biomaterial scaffolds in vascular tissue engineering applications lately, no ideal platform has been provided for small diameter synthetic vascular grafts mainly due to the thrombosis issue. Endothelium is the only known completely non-thrombogenic material; so, functional endothelialization onto vascular biomaterials is critical in maintaining the patency of vascular networks. Bacterial cellulose (BC) is a natural biomaterial with superior biocompatibility and appropriate hydrophilicity as potential vascular grafts. In previous studies, surface modification of active peptides such as Arg-Gly-Asp (RGD) sequences onto biomaterials has been proven to achieve accelerated and selective endothelial cell (EC) adhesion. In our study, we demonstrated a new strategy to remotely regulate the adhesion of endothelial cells based on an oscillating magnetic field and achieve successful endothelialization on the modified BC membranes. In details, we synthesized bacterial cellulose (BC), magnetic BC (MBC), and RGD peptide-grafted magnetic BC (RMBC), modified with the HOOC-PEG-COOH-coated iron oxide nanoparticles (PEG-IONs). The endothelial cells were cultured on the three materials under different frequencies of an oscillating magnetic field, including "stationary" (0 Hz), "slow" (0.1 Hz), and "fast" (2 Hz) groups. Compared to BC and MBC membranes, the cells on RMBC membranes generally show better adhesion and proliferation. Meanwhile, the "slow" frequency of a magnetic field promotes this phenomenon on RMBC and achieves endothelialization after culture for 4 days, whereas "fast" inhibits the cellular attachment. Overall, we demonstrate a non-invasive and convenient method to regulate the endothelialization process, with promising applications in vascular tissue engineering.

“…TGA curves involve the dehydration of sample due to the breakage of the hydrogen bonds associated with water molecules as the first reduction in mass occurred at 25–200°C. The second stage in TGA curves is related to the depolymerization and pyrolytic decomposition at 220–415°C attributed to the possible thermal degradation and final production of H 2 O, CO, and CH 4 due to decomposition at high temperature 40–42 . At onset temperature of thermal degradation, raw BC (Figure 4a) and BC/H 2 O 2 (Figure 4b) lost about 6.07% and 3.77% of their initial weight in the first stage due to dehydration and loss of surface bonds.…”

The most effective approach for wound healing improvement is entrapping and controlling the oxygen in a biocompatible polymer matrix through introducing hydrogen peroxide. In the research, the bacterial cellulose (BC) layers were oxygenated as a safe and excellent hydrogel to accelerate the wound healing process. Indeed, the hydrogel‐containing hydrogen peroxide was obtained using the treatment of dry BC with 3% hydrogen peroxide for 5 h. The morphology, thermal behavior, crystalline and chemical structures, mechanical properties, water vapor permeability, degree of porosity, oxygen release, water holding capacity, and drying time of the treated layers were investigated. Furthermore, the calculated porosity showed about seven times more pore area. The dissolved oxygen results indicated the well‐trapped oxygen in BC with a prolonged‐release time of 20 days. Moreover, the 100% antibacterial and antifungal activities and excellent wound healing properties without cytotoxic effects specified the ability of BC to trap and release oxygen for efficient wound healing. Hence, the study introduces a functionalized naturally driven hydrogel layer with oxygen delivery, safe antimicrobial properties, and prolonged drying time.

“…Following the trend of developing biomimetic materials with special surface properties (for example superhydrophobic materials structurally resembling the lotus leaf [ 203 , 204 ]), bacterial cellulose became of interest to scientists working on hybrid materials. Thus, biocomposites with improved interfacial wettability were created by chemical cross-linking with oligopeptides, promoting tissue repair, which is of high importance in regenerative medicine [ 205 ]. Recent investigations pointed out the advantages of using bacterial cellulose in tympanic grafts, which enhances the surgical procedure by improving the healing ability after the graft is accepted by the organism.…”

Bacterial Cellulose—A Remarkable Polymer as a Source for Biomaterials Tailoring

Nowadays, the development of new eco-friendly and biocompatible materials using ‘green’ technologies represents a significant challenge for the biomedical and pharmaceutical fields to reduce the destructive actions of scientific research on the human body and the environment. Thus, bacterial cellulose (BC) has a central place among these novel tailored biomaterials. BC is a non-pathogenic bacteria-produced polysaccharide with a 3D nanofibrous structure, chemically identical to plant cellulose, but exhibiting greater purity and crystallinity. Bacterial cellulose possesses excellent physicochemical and mechanical properties, adequate capacity to absorb a large quantity of water, non-toxicity, chemical inertness, biocompatibility, biodegradability, proper capacity to form films and to stabilize emulsions, high porosity, and a large surface area. Due to its suitable characteristics, this ecological material can combine with multiple polymers and diverse bioactive agents to develop new materials and composites. Bacterial cellulose alone, and with its mixtures, exhibits numerous applications, including in the food and electronic industries and in the biotechnological and biomedical areas (such as in wound dressing, tissue engineering, dental implants, drug delivery systems, and cell culture). This review presents an overview of the main properties and uses of bacterial cellulose and the latest promising future applications, such as in biological diagnosis, biosensors, personalized regenerative medicine, and nerve and ocular tissue engineering.
