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

Then, a nano-sized encapsulated anticancer drug, methotrexate (MTX), was successfully embedded in the synthesised dendrimer complex namely G3.0-Fu/MTX. Newly synthesised G3.0-Fu/MTX

Breast cancer (BC), a common malignancy, is intractable at present. Cuprous oxide nanoparticles (Conps) are new nanoparticles crucial in inhibiting tumor progression according to early studies, but their role in BC remains unclear.

Silver nanoparticles (AgNPs) are well known for their unique physical and chemical properties, which can be incorporated into a wide range of applications. The growing resistance of microorganisms to antimicrobial compounds promoted the use of AgNPs in antimicrobial therapy. AgNPs can be obtained using physical and chemical methods, but these technologies are highly unfriendly to nature and produce large amounts of side compounds (for example, sodium borohydride and N,N-dimethylformamide). Therefore, alternative technologies are required for obtaining AgNPs. This report focuses on the biosynth

Abstract:

In spite of the widespread use of the chemical reduction method to obtain silver nanoparticles, the nanoparticle yield is often low due to a required addition of small volumes of diluted metal ions to a solution containing a reducer. Higher yields can be obtained following an alternative method, in which the reducer is added to a greater volume of silver ions in the solution. In this study, protocols for both methods are detailed and compared, using characterization tools such as UV-vis spectrometry, dynamic light scattering (DLS), and zeta potential measurements.
