Abstract:
The dynamic light scattering (DLS) technique was applied in order to assess the zeta potential of the plasma membrane of human cells. At pH 7.4, the cell zeta potential for different types of cells showed variations over a wide range and was equal to -19.4 0.8 mV for HeLa cells and -31.8 1.1 mV for erythrocytes. The difference could presumably be attributed to the differences in the biochemical composition of the cell plasma membrane. As a result of the heating of HeLa cells, the zeta potential shifted towards more negative voltages by 4.2 mV. An increase in the zeta potential correlated with

Abstract:
Itraconazole (ITZ) is a potent antifungal agent. Its oral administration is associated with systemic toxicity, and its efficacy in ocular formulations is limited. This study aims to enhance ITZ’s ocular permeation and antifungal efficacy by loading it into deformable liposomes (DLs) based on Tween 80 (T) or Poloxamer 188 (P). Moreover, ITZ was loaded into biopolymer-coated DLs to augment its ocular availability. ITZ-loaded DLs were coated with hyaluronic acid (HA-DLs), chitosan (CS-DLs), or a layer-by-layer coating (CS/HA-DLs). These formulations were further laden into pH-sensitive in situ ge

Abstract:
Size and zeta potential are critical physicochemical properties of nanoparticles (NPs), influencing their biological activity and safety profile. These are essential for further industrial upscale and clinical success. However, the characterization of polydisperse, non-spherical NPs is a challenge for traditional characterization techniques (ex., dynamic light scattering (DLS)). In this paper, superparamagnetic iron oxide nanoparticles (SPIONs) were coated with polyvinyl alcohol (PVAL) exhibiting different terminal groups at their surface, either hydroxyl (OH), carboxyl (COOH) or amino (NH2) e

ABSTRACT Corrosion products can deposit on the critical surfaces of feed water flow venturis that are used to measure mass flow rates. Such fouling leads to erroneous values of mass flow rates, thereby causing derating of nuclear power plants. A number of observations suggest that such deposition is a consequence of superficial surface electrical charges that are induced on the surfaces of the corrosion products and flow control venturis. A measure of this surface charge is zeta potential, (i.e. the potential difference between the outer Helmholtz plane of the electrical double layer formed at

Properties were analyzed by FTIR, TGA, DLS, zeta potential, AFM and SEM. The results showed that nanocellulose with a fiber like structure was preferentially obtained after 60 min in contact with sulfuric acid.

Abstract:
In recent years, the importance of nanoparticle synthesis and application has increased, and as a result, more research has been conducted on nanoscience and nanotechnology. In particular, research on the production of environmentally friendly, less wasteful, low-cost, and multifunctional nanomaterials has increased dramatically. Some studies have been conducted on natural organic waste materials such as coconut husk, nutmeg seed, mint leaves, coffee beans, and tea leaves for producing nanostructures. Using organic waste materials as a source of nanostructures helps us save on disposal costs a

Abstract:
Abstract Poly(ionic liquid) (PILs) are a rapidly growing subclass of polyelectrolyte which combines the diverse functionality of ionic liquids with the mechanical integrity, processability, and macromolecular design of polymeric systems. PIL properties are highly dependent on their counterion, which can be easily exchanged to tailor their material properties. Incorporation of metal halide counterions (FeCl4−, CoCl42−, etc.) into the PIL structure results in magnetically responsive metal-salt composites known as magnetic-PILs (MPILs). MPILs are predominately formed through electrostatic binding

Abstract:
Cellulose and STOC (Soluble Tempo-mediated Oxidized Cellulose) were chemically modified with different alkyl succinic anhydride with varying chain lengths including succinic anhydride (SAC0), 2-Octen-1-ylsuccinic anhydride (SAC8), or 2-dodecen-1-yl succinic anhydride to fabricate novel emulsifiers to stabilize the fish oil-in-water emulsion system. After the pretreatment-Tempo-mediated Oxidation, STOC was characterized by Fourier transformed infrared (FTIR), Carboxylated content, Degree of Oxidation, Scanning electron microscopy (SEM), and Gel Permeation Chromatography (GPC). Based on it, the
