The green synthesis of silver (Ag) and zinc oxide (ZnO) nanoparticles (NPs), as well Ag/Ag2O/ZnO nanocomposites (NCs), using polar apolar extracts Chlorella vulgaris, offers a sustainable method for producing nanomaterials with tunable properties. impact the environment nanomaterials’ characteristics on cytotoxicity was evaluated by examining reactive species production their effects mitochondrial bioenergetic functions. Cytotoxicity assays PC12 cells, cell line originated from rat pheochromocytoma, an adrenal medulla tumor, demonstrated that Ag/Ag2O NPs synthesized (Ag/Ag2O A) P) exhibited significant cytotoxic effects, primarily driven Ag+ ion release disruption function. However, it is more likely organic content, rather than size, influenced anticancer activity, commercial Ag NPs, despite smaller crystallite sizes, exhibit less effective activity. ZnO P showed increased oxygen (ROS) generation, correlated higher cytotoxicity, while A produced lower ROS levels, resulting in diminished effects. comparative analysis revealed differences LD50 values toxicity profiles. Differentiated cells resistance to ZnO, AgNPs Ag/Ag2O-based materials had similar both types. This study emphasizes crucial role bioactive compounds C. vulgaris modulating nanoparticle surface chemistry, cytotoxicity. results provide valuable insights designing safer biomedical applications, especially targeting tumor-like exploring relationships between polarity, capping agents, nanocomposite structures.

Analysis of Tetracycline Modification Based on g-C3N4 Photocatalytic Degradation

Inorganics, Journal Year: 2025, Volume and Issue: 13(3), P. 77 - 77

Published: March 7, 2025

To address challenges in antibiotic wastewater treatment, we synthesized a series of graphitic carbon nitride (g-C3N4)-based photocatalysts (BCN, PCN, TCN, BTCN, and TCNE-modified PTCN) via defect engineering. TCNE modification disrupted the triazine ring-bridging amino network PTCN, forming porous structure with enhanced specific surface area validated by SEM/TEM while retaining graphene-like framework confirmed XRD/FTIR. Photoluminescence (PL) analysis revealed prolonged photogenerated carrier lifetime improved separation efficiency achieving 89.10% degradation chlortetracycline hydrochloride under visible light—1.65-fold higher than pristine g-C3N4. Mechanistic studies identified superoxide radicals (•O2−) as dominant active species, generated O2 activation at sites efficient electron-hole utilization. Optimized conditions enabled PTCN to maintain high activity across broad pH range retain 82.59% after five cycles. This work advances defect-engineered photocatalyst design for adaptable, high-performance degradation, offering practical insights remediation.

Nanoparticles are small structures that differ in terms of their shape and composition; high surface-to-volume ratio is responsible for unique properties make them perfect mediators the delivery substances. do not only include metallic spheres but also complex polysaccharides capsule viruses or bacterial protein complexes (which can be considered bionanoparticles), which 1–100 nm size. Although nanoparticles most widely studied from medical perspectives, potential applications almost limitless. One such promising use functional plant protection against diseases. precise decreases need other chemical compounds, thanks to increased product stability a target site, production often burdened by large quantities toxic wastes. This problem limited if we apply bioreactor green synthesis method, includes with microorganisms. Bacteria produce internally, externally, producing metabolites used nanoparticle directly, e.g., surfactants, indirectly as reducing agents metal production. Regardless source nanoparticles, they processes disease/pathogen detection disease suppression. The endless variety materials possible modifications subjected makes it impossible predict how will future. Nevertheless, this study, would like turn attention fact although viewed synthetic structures, ever-present microbial world play an important part intermicrobial interactions. As usefulness has been tested over years co-evolution, may useful look future directions fascinating technology.
