“…This composite exhibited high adsorption selectivity toward histidine-rich proteins, which was utilized for isolating hemoglobin from human whole blood, and also for isolating a polyhistidine-tagged recombinant protein from Escherichia coli lysate, namely Staphylococcus aureus enterotoxin B [77]. For macromolecular separation, cellulose acetate nanocomposite ultrafiltration membranes were fabricated using 2D layered nanosheets, e.g., GO and exfoliated molybdenum disulfide (MoS 2 ), and were successfully tested using macromolecular bovine serum albumin [79].…”

“…In addition to its advantageous combination with nanocarbon materials, nanocellulose is an appealing material for biomedical applications due to its tunable chemical fluorescence and luminescence [26,71,72] photothermal activity [56], hydrolytic stability [61], nanoporous character and high adsorption capacity [49,61]. Nanocellulose/nanocarbon composites can therefore be used in a wide range of industrial and technological applications, such as water purification [22,29,43,49,54,56,61,[73][74][75][76], the isolation and separation of various molecules [22,74,[77][78][79], energy generation, storage and conversion [21,23,44,47,64,[80][81][82][83][84][85], biocatalysis [86], food packaging [67][68][69]87], construction of fire retardants [48], heat spreaders [70] and shape memory devices [38,[88][89][90].

Nanocellulose/nanocarbon composites are newly emerging smart hybrid materials containing cellulose nanoparticles, such as nanofibrils and nanocrystals, and carbon nanoparticles, such as “classical” carbon allotropes (fullerenes, graphene, nanotubes and nanodiamonds), or other carbon nanostructures (carbon nanofibers, carbon quantum dots, activated carbon and carbon black). The nanocellulose component acts as a dispersing agent and homogeneously distributes the carbon nanoparticles in an aqueous environment. Nanocellulose/nanocarbon composites can be prepared with many advantageous properties, such as high mechanical strength, flexibility, stretchability, tunable thermal and electrical conductivity, tunable optical transparency, photodynamic and photothermal activity, nanoporous character and high adsorption capacity. They are therefore promising for a wide range of industrial applications, such as energy generation, storage and conversion, water purification, food packaging, construction of fire retardants and shape memory devices. They also hold great promise for biomedical applications, such as radical scavenging, photodynamic and photothermal therapy of tumors and microbial infections, drug delivery, biosensorics, isolation of various biomolecules, electrical stimulation of damaged tissues (e.g., cardiac, neural), neural and bone tissue engineering, engineering of blood vessels and advanced wound dressing, e.g., with antimicrobial and antitumor activity. However, the potential cytotoxicity and immunogenicity of the composites and their components must also be taken into account.

“…Among different cellulose esters, cellulose acetate (CA) is very common due to desirable properties such as good toughness, high biocompatibility, good desalting, high potential flux, and relatively low cost [5,13]. However, neither the fouling ability nor the chemical and thermal resistance of cellulose acetate is satisfactory [8,14,15].…”

Biodegradable cellulose acetate (CA) membranes were prepared via phase inversion induced by immersion precipitation method. Acetic acid and deionized water were used as solvent and non‐solvent, respectively. The modifying effect of gelatin and zinc oxide (ZnO) nanoparticles additives was investigated on the membranes in terms of water flux, protein rejection percentage, and fouling ability during two hours of bovine serum albumin separation from aqueous solution. Specimens were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), tensile test, contact angle technique, and porosity measurement. The incorporation of gelatin and ZnO nanoparticles into the CA matrix increased the porosity coefficient and hydrophilicity. Moreover, gelatin improved the tensile properties of the membrane.

“…Organic and inorganic nanoparticles (NPs)/NCs are two major groups of nanomaterials with various therapeutics and industrial applications [7]. NCs are defined as multiphase solid materials with one or more dimensions in 1 to 100 nm [8][9][10]. Calcium phosphate nanocomposite (CaPhos NC) is one of the most important inorganic NCs which is a structural component of teeth and bones scaffold [11].…”

Urinary tract infections (UTIs) are the reason for 15-70% of urinary stone disease (USD). Many diabetic patients suffer from USD resulting from bacterial infections by multi drug resistant (MDR) bacteria such as Staphylococcus aureus ATCC 43300. These bacteria can enhance struvite stones' formation in diabetic patients with UTIs. In this regard, hyperglycemia, proteinuria, and using of metformin drug may be important factors. Three parameters including glucose, metformin, and protein with their three levels of concentrations were determined by experimental design of Taguchi method to obtain optimized formation of struvite stones. Artificial urine medium was utilized for simulation of natural human urine. Scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDAX) techniques were applied for evaluation of morphology and elemental compositions of formed calcium phosphate. This study showed highest concentration of struvite stones (0.512 g/L) under interaction conditions of 3×2×2 levels respectively for glucose, metformin, and protein. Results of SEM and EDAX analyses demonstrated clumped crystallite property and flower-like nanocomposites (NCs) of struvite stones with contribution of calcium (160.8) and phosphate (131.4) elements. It may be concluded from this investigation that therapy of MDR bacteria, hyperglycemia, and proteinuria can decrease urinary stone formation in diabetic patients by having UTIs.
