Abstract Excessive consumption of antibiotics is considered one the top public health threats, this necessitates development new compounds that can hamper spread infections. A facile green technology for biosynthesis Zinc oxide nanoparticles (ZnO NPs) using methanol extract Spirulina platensis as a reducing and stabilizing agent has been developed. bunch spectroscopic microscopic investigations confirmed biogenic generation nano-scaled ZnO with mean size 19.103 ± 5.66 nm. The prepared NPs were scrutinized their antibacterial antibiofilm potentiality, inhibition zone diameters ranged from 12.57 0.006 mm to 17.33 (at 20 µg/mL) variety Gram-positive Gram-negative pathogens, also significant eradication biofilms formed by Staphylococcus aureus Klebsiella pneumoniae 96.7% 94.8% respectively was detected. free radical scavenging test showed promising antioxidant capacity (IC 50= 78.35 µg/mL). Furthermore, anti-inflammatory role detected HRBCs-MSM technique revealed an efficient stabilization red blood cells in concentration-dependent manner. In addition, have anticoagulant antitumor activities well minimal cytotoxicity against Vero cells.

Abstract Biogenic synthesis of metal nanoparticles offers a sustainable alternative to traditional methods that often rely on toxic reducing agents, offering an environmentally friendly approach nanoparticle production. The use nanofibrous substrates, algal nanofibers (Polyacrylonitrile (PAN)/ Cystoseira barbata ( Cb )), for the reduction process enhances efficiency formation, providing larger surface area reaction and ensuring uniform distribution synthesized nanoparticles. Following biogenic Ag their stabilization with xanthan gum (XG), resulting PAN/ /Ag@XG catalyst demonstrates excellent reusability, maintaining its activity structural integrity even after multiple cycles use. XG also ensures long‐term shelf life by preventing aggregation. Additionally, material exhibits antimicrobial against E. coli S. aureus . Its dual functionality—targeting harmful pathogens while avoiding secondary pollution—positions them as eco‐friendly solution advanced water purification disinfection systems.

Organic dye pollutants that are progressively used in modern chemical industries, emerged as a major source of water contamination. A promising eco-friendly and simple approach to purification is the heterogeneous photocatalytic process uses various metal oxide semiconductors presence light, initiating oxidation-reduction reactions resulting degradation. The aim this study was investigate influence coprecipitation synthesis methods on photodegradation efficiency. ZnFe based photocatalysts were synthesized using two different methods: low (LS) supersaturation high (HS) thermally activated at 100, 300, 500 700?C. Structural textural characterisation carried out their efficiency methylene blue test reaction studied. LS samples treated 100 300?C exhibited very (less than 10 %) when compared HS same temperatures (75 85 %). 700 improved (67 75 with increase thermal treatment temperature difference between decreased. Such behaviour could be explained by structural properties originated from methods.
