Fracture Behaviour of Bacterial Cellulose Hydrogel: Microstructural Effect
A growing interest in fibrous biomaterials,especially hydrogels,is due to a fact that they promise a good potential in biomedical applications thanks to their attractive biological properties and similar microstructure that mimics its in vivo environment. Since they are usually employed as a main load-bearing-component when introduced into body environment, a comprehensive unde...

Time-dependent rheological behaviour of bacterial cellulose hydrogel
This work focuses on time-dependent rheological behaviour of bacterial cellulose (BC) hydrogel. Due to its ideal
biocompatibility, BC hydrogel could be employed in biomedical applications. Considering the complexity of
loading conditions in human body environment, time-dependent behaviour under relevant conditions should
be understood. BC specimens are produced by Gluconacetobacter xyli...

Natural Cellulose Fibers from Eulaliopsis Binata
Natural cellulose fibers extracted from Eulaliopsis Binata (EB) were systematically investigated in this paper. Fourier-transform infrared (FTIR), Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD) were used to investigate the chemical composition, morphological structure and crystalline structure of the resulting fibers. Furthermore, some basic physical properties of the EB fibe...

Ordered manufactured bacterial cellulose as biomaterial of tissue engineering
Abstract: Bacterial cellulose (BC) is one of the best nanosizedfibrous materials produced byAcetobacter xylinumin nature. Every bacteria secretes one cellulosefibril, which pushes bacteria forward and leads to cellulose aggradation and bacterial movement in a straight line. Usually, A. xylinummoves randomly in all directions and BC in irregular network is formed when it is cultured in static liq...

Flexible Supercapacitor based on Bacterial Cellulose Paper Electrodes
Herein, we report on supercapacitors based on a new freestanding and flexible electrode, which can be fabricated with bacterial cellulose (BC), multi-wall carbon nanotubes (MWCNTs), and polyaniline (PANI). Due to the porous structure and electrolyte absorption properties of the BC paper, the flexible BC-MWCNTs-PANI hybrid paper electrode exhibits appreciated specific capacitance (656 F g-1 at a di...

Evaluation of Bacterial Cellulose/Hyaluronan Nanocomposite Biomaterials
Bacterial cellulose (BC) is useful in the biomedical field because of its unique structure and properties. The high nano-porosity of BC allows other materials to be incorporated and form reinforced composites. Here we describe the preparation and characterization of novel BC/hyaluronan (HA) nanocomposites with a 3-D network structure. BC/HA was obtained using a solution impregnation method. Elemen...

Preparation and Optical Properties of ZnO-Cellulose Nanocomposites.
ZnO-cellulose nanocomposites are prepared by mixing nanocrystalline cellulose (NCC) colloids with ZnAc2·2H2O alkaline solution by ultrasound assisted approach. The sample is characterized by X-ray diffraction, Scanning electron microscope (SEM), Transmission electron microscopy (TEM), Thermogravimetric analyzer (TGA), UV-Vis spectroscopy and spectrofluorometer. The results show that ZnO nanoparti...

Nano-cellulose 3D-networks as controlled-release Drug Carriers
Abstract：
Bacterial cellulose (BC) membranes are used as the carrier for berberine hydrochloride and berberine sulphate to produce a new controlled release system. Release studies and transdermal experiments were carried out in vitro. Carrier BC can significantly extend the drug release time, in contrast to existing commercial carriers. Freeze-dried BC membranes 10 mm thick were optimized fo...

In situ nano-assembly of bacterial cellulose–polyaniline composites
Abstract：
Bacterial cellulose (BC), produced by Gluconacetobacter xylinum, consists of ribbon-shaped nano-fibers in web-like structures. Polyaniline (PAni) is a conductive polymer, the conductivity of which is related to the synthesis and doping process. In this paper, we report on the in situ nano-assembly of BC nanofibers and PAni to enhance the electronic conductivity. PAni could be synthesiz...
