Abstract Novel sulfur zinc nanoparticles functionalized with thioglycolic acid were synthetized via hydrothermal route and tested in a solar radiation-based dye photodegradation process. These characterized, the findings revealed that was strong capping ligand for generation of specific surface area 36.82 m 2 /g 7.15 nm average nanocrystal size. The cubic wurtzite phases these confirmed X-ray diffraction. quantum confinement effect caused larger energy band gap blue shift absorbance contrast to bulk zinc. improved adsorption effectiveness proved remove methylene from aqueous solutions. They can 30.92 mg/g molecule. To understand synergy between photocatalysis, used analyze prior experimental measurement isotherms kinetics. rationalization on performed calculated statistical physics parameters including estimation – energy. Dye molecules exhibited physical interactions energies 25.92–23.31 kJ/mol. sunlight-based photocatalytic activity demonstrated 91.1% degradation efficiency 180 min. Overall, remained almost unchanged after five consecutive cycles 88 ± 3%. results indicate sustainable be applied cleaning industrial urban fluids polluted by hazardous organic compounds like molecules.

A Comparative Study of Green and Chemically Prepared PEGylated Zinc Sulfide Nanoparticles (ZnS‐NPs) for Biological Applications

ChemistrySelect, Journal Year: 2024, Volume and Issue: 9(43)

Published: Nov. 1, 2024

Abstract This study compares chemical and green synthesized zinc sulfide nanoparticles for multiple biological properties. A synthesis approach is utilized to synthesize PEGylated ZnS‐NPs while the bulbs of Fritillariae cirrhosae bulbus are synthesis. After extensive characterization, NPs examined multifunctional properties such as antimicrobial, antioxidant, in vitro anticancer, blood compatibility. Our found that results higher yield better dispersion behavior. However, possessed increased antibacterial antiparasitic potential against Leishmania tropica resulted significant inhibition Staphylococcus aureus ( S. ) Bacillus subtilis B. with minimum inhibitory concentration (MIC) 0.156 0.312 mg/mL, respectively IC50 115.21 128.5 µg/mL were observed promastigote amastigote forms parasite. Furthermore, Fritillaria cirrhosa F. cirrhosa) slightly improved antioxidant anticancer MCF‐7 breast cancer cells. Despite differences properties, did not result hemolytic behavior thus demonstrating compatible nature It was evident from present techniques only different physicochemical characteristics but also significantly influence bio‐interaction obtained ZnS‐NPs.
