Background: The usages of biosynthesized nanomaterials for microbial pathogens’ fighting have numerous rationales and effectiveness. Skin microbes could acquire drug-resistance that needs innovative approaches overcoming. Objectives: Phytosynthesized silver nanoparticles (AgNPs) with Commiphora myrrh resin extract (MR) their nanoconjugates chitosan (Cht) were fabricated assessed as potential antimicrobial agents controlling antibiotic-resistant skin pathogens, Materials methods: AgNPs biosynthesis was achieved within MR solution they composited Cht. syntheses validated using infrared spectroscopy electron microscopy loaded onto cotton textiles, then all nanomaterials/textiles inhibiting pathogens Staphylococcus aureus Candida albicans. Results: Nanomaterials’ characterization appointed the mean size MR-synthesized to be 22.58 nm, whereas diameter Cht/MR/AgNPs nanocomposites 130.34 nm carry +25.9 mV charges. assessment interactions between employed materials. textiles MR/AgNPs effectively inhibit growth albicans, most powerful. scanning confirmed action toward pathogens; mostly lysed deformed 12 h exposure nanocomposites. Conclusions: nanocomposite provided potent actions pathogens.

ABSTRACT The incorporation of waste plant residues into practical applications, particularly as a sustainable source green dyes in textiles, is increasingly recommended by the global community. This research investigates potential Rangoon creeper flowers and madder roots for silk dyeing through environmentally friendly methodologies. Therefore, extraction procedures were conducted suitable mediums applied to fabric before after microwave (MW) treatment durations up 10 min. Similarly, response surface methodology was employed assess significance various parameters, which influence shade development enhance colorfastness. results indicate that subjecting acidic binary extracts roots, along with fabric, 6 min radiation at 700 W an effective condition achieving colorfast shades, when mordanting Al, Fe salts, tannic acid single their solution eco‐chemical agents. highest color strength (K/S = 15.0) obtained using extract MW treatment. Hence, evaluation based on standard methods such ISO protocols lightfastness, wash fastness, rub fastness demonstrates employing selected shades produced under conditions both time energy‐efficient, yielding stable hues rated from good excellent. study suggests utilizing addition statistical methodologies like central composite design exploring novel dye‐yielding plants, coupled eco‐mordanting techniques, holds promise obtaining desirable shades.

The escalating challenge of antibacterial resistance has driven the widespread use silver nanoparticles (AgNPs) due to their potent antimicrobial properties. AgNPs can be synthesised through diverse methods, spanning conventional chemical and physical routes increasingly favoured biosynthesis approach. While offering environmental advantages, ecological impact biogenically synthesized AgNPs, especially on aquatic ecosystems, requires thorough evaluation. renal system, critical for maintaining physiological homeostasis via nephron-mediated waste removal, fluid regulation, electrolyte balance, is highly vulnerable toxicant-induced damage, which negatively affect organismal fitness. This study aimed assess nephrotoxic effects using entirely "green" zebrafish after 96-h exposures three distinct concentrations alongside a control group. Acridine orange fluorescence microscopy revealed dose-dependent histopathological alterations in tissues. Specifically, at 0.031 μg/L 0.250 μg/L, significant changes were observed, including glomerular shrinkage, proliferation hematopoietic tissue, dissociation dilation tubules, melanomacrophage aggregation. At 5.000 prolonged exposure beyond 48 h indicated potential tissue cell renewal, suggesting possible compensatory response. These results demonstrate sensitivity kidneys emphasize imperative comprehensive vivo toxicity testing, irrespective synthesis method, accurately evaluate adverse impacts ensure preservation ecosystem integrity.
