Synthesis and Characterization of Blended Cellulose Acetate Membranes

Abdullah M. Asiri et al.

Summary: The casting and preparation of ultrafiltration ZnO modified cellulose acetate membrane (CA/ZnO) were investigated in this work. The results showed that ZnO modified CA membranes have higher surface pore size, pore density and porosity, and improved surface hydrophilicity compared with pure CA membranes, but lower flux.

New biodegradable nanoparticles-in-nanofibers based membranes for guided periodontal tissue and bone regeneration with enhanced antibacterial activity

Dina Abdelaziz et al.

Summary: A new series of nanofibrous scaffolds were prepared in this study for GTR/GBR applications, with enhanced cell viability and antibacterial activity through the incorporation of hydroxyapatite nanoparticles and green-synthesized silver nanoparticles, respectively. The scaffolds showed a desirable degradation profile, losing around 40-70% of their mass in 8 weeks, making them promising for both GTR and GBR applications.

Simple conversion of 3D electrospun nanofibrous cellulose acetate into a mechanically robust nanocomposite cellulose/calcium scaffold

Joshua Lee et al.

Summary: Cellulose and its derivatives are commonly used as nanofibrous biomaterials, but research on obtaining 3D cellulose nanofibers is limited. This study presents a simple method for converting electrospun 3D cellulose acetate/lactic acid nanofibers into a 3D cellulose/calcium lactate nanocomposite matrix, resulting in a stronger and more cell-friendly material suitable for bone tissue engineering. The successful conversion was verified through various analytical techniques, and the scaffolds were found to provide a suitable environment for cell growth and infiltration.

Tuning the pore features of cellulose acetate/cellulose triacetate membranes via post-casting solvent treatment for forward osmosis

Fahhame Jazini et al.

Summary: In this study, a solvent exchange method was used to treat cellulose acetate/cellulose triacetate forward osmosis (CA/CTA FO) membrane, resulting in increased micropores and mesopores, and improved reverse salt flux and pure water flux by 65% and 20% respectively. The treatment also led to a 55% increase in selectivity and a 40% reduction in structural parameter, contributing to enhanced membrane performance.

Magda M. Velasquez-Rojas et al.

Summary: Graphene oxide powder and graphene oxide paper were covalently functionalized with AB15C5 and AB18C6 ethers under solvent-free gas-phase treatment, followed by complexation with potassium and sodium cations. Characterization using various techniques showed an increase in contact angle and a decrease in surface free energy for functionalized samples, with better complexation observed with potassium using AB18C6.

Influence of calcium ion-modified implant surfaces in protein adsorption and implant integration

Eduardo Anitua et al.

Summary: This study investigated the difference in protein adsorption pattern and in vivo responses between surfaces modified with calcium ions and standard titanium implant surfaces, revealing a stronger thrombogenic protein adsorption pattern on calcium ion surfaces correlated with higher levels of implant osseointegration. Therefore, more effective implant surfaces may help reduce invasive surgeries, shorten healing times, and lower intervention costs.

Cellulose acetate-polyvinyl alcohol blend hemodialysis membranes integrated with dialysis performance and high biocompatibility

Ofaira Azhar et al.

Summary: In this study, Cellulose Acetate (CA) hemodialysis membrane was modified using Polyvinyl Alcohol (PVA) and Polyethylene Glycol (PEG) additives to enhance filtration capability and biocompatibility. The synthesized membranes showed improved water flux, solute permeation, and protein retention, as well as reduced platelet adherence and hemolysis ratio compared to conventional CA membranes. Overall, the fabricated CA-PVA hemodialysis membranes displayed higher efficiency and biocompatibility, making them a promising option for clinical use.

Porous polymeric membranes: fabrication techniques and biomedical applications

Amane Shiohara et al.

Summary: Porous polymeric membranes have great potential in biological and biomedical applications due to their structural flexibility, versatile surface chemistry, and biocompatibility. Common fabrication techniques include track etching, nanoimprinting, block-copolymer self-assembly, and electrospinning, which allow for precise control of pore size, shape, density, and surface properties. Main applications of these membranes include drug delivery, tissue engineering, biosensing, and bioseparation, with discussions on the role of membrane material and pore morphology for each specific application, fabrication challenges, and future prospects.
