Toxic effect of mussel Mytilus galloprovincialis exposed to Ag-TiO and ZnTiO-TiO bicomponent nanoparticles.

Nanoparticles (NPs) are widely used in various fields, including antifouling paints for ships and industrial structures submerged in water. The potential impact of NPs on aquatic organisms, particularly their potential toxicity, is a significant concern, as their negative impact has been relatively poorly studied. In this study, we evaluated the effect of different concentrations of bimetallic Ag-TiO₂ and ZnTi₂O₄-TiO₂ NPs, which could potentially be used in antifouling coatings, on the hemocytes of the Mediterranean mussel Mytilus galloprovincialis.

Influence of Sc substitution on the structure and properties of NASICON-type NaScR(PO) (R = Eu, Tb, Dy) phosphors.

NaScR(PO) (R = Eu, Tb, Dy; 0 ≤ ≤ 0.2) phosphors were synthesized by a high-temperature solid-state reaction. Sc : R ratios for the NSP:R samples were determined by ICP-MS, EDX-SEM and TEM-EDX measurements.

New PMMA-Based Hydroxyapatite/ZnFeO/ZnO Composite with Antibacterial Performance and Low Toxicity.

Polymethylmethacrylate (PMMA) is the most commonly used bone void filler in orthopedic surgery. However, the biocompatibility and radiopacity of PMMA are insufficient for such applications. In addition to insufficient biocompatibility, the microbial infection of medical implants is one of the frequent causes of failure in bone reconstruction.

AFM methods for studying the morphology and micromechanical properties of the membrane of human buccal epithelium cell.

Using AFM methods in air under normal conditions in a wide range of local force effects ([Formula: see text]< 40 μN) the relief, functional micromechanical properties (elasticity coefficient [Formula: see text], Young's modulus [Formula: see text], elastic [Formula: see text] and plastic [Formula: see text] deformations) and adhesive properties (work [Formula: see text] of adhesive forces [Formula: see text]) of the membranes of living adult cells of human buccal epithelium were studied in the presence of a protective layer < 100 nm of buffer solution that prevented the cells from drying. Almost all geometric and functional characteristics of the membrane in the local approximation at the micro- and nanolevels are affected by size effects and obey the laws of fractal geometry. The Brownian multifractal relief of the membrane is characterized by dimension [Formula: see text] < 2.
