Because of their acute toxicity and long-lasting effects on the environment such as chemical accidents, agricultural runoff, and industrial effluents, has raised concerns around the world. Semiconductor-based photocatalysis has gained prominence for its ability to degrade organic contaminants comprehensively, providing a potential solution to the limitations of the conventional methods. This study addresses the environmental repercussions of dye contamination and explores the utilization of active semiconductor photocatalysts for effective wastewater treatment. Our focus lies in synthesizing CZTS through the hydrothermal route, a method gaining traction for its simplicity and environmental viability. To augment the photocatalytic efficiency of semiconductor materials, graphene oxide (GO) has been introduced with varying GO concentrations of 5% and 10%. Additionally, the study explores the performance of CZTS nanoparticles with varying GO concentrations for antibacterial applications against eight Gram-positive/negative bacterial strains and its catalytic prowess in the photodegradation of methylene blue dye under ultraviolet light.

“…Microbial growth was determined by adding 20 µL of 2,3,5-Triphenyl-tetrazolium chloride (0.5%) after incubation to each well and incubating for 30 minute at 37°C . The lowest concentration of the extracts that completely inhibit macroscopic growth was determined as minimum inhibitory concentrations (MICs) (Qader, et al 2022).…”

In this study, eco-friendly, low-cost and high-antimicrobial activity Polyvinyl alcohol(PVA)/Chitosan (CHT)/Clay/Oil nanocomposite hydrogels were prepared via freeze-thaw (F-T) method. Montmorillonite (MMT) and nanoclay (NC) were added as clay to PVA/CHT/Clay/Oil hydrogels. MMT and NC decreased the number of F-T cycles in the hydrogel and increased the surface hydrophilicity of the hydrogels. Clove, aloe vera and argan oil were added as oil to PVA/CHT/CLAY mixtures. Hydrogels containing clove oil showed antimicrobial activity against eight microorganisms (Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, Klebsiella pneumoniae ATCC 70603, methicilline resistant Staphylococcus aureus ATCC 43300 (MRSA), Salmonella enteritidis ATTC 13076, Sarcina lutea ATCC 9341, Bacillus cereus ATTC 11778, Candida albicans NRRL Y-417). Nanocomposite hydrogels containing clove oil , have been found to have high antimicrobial activity, skin adhesion and swelling degree. Contact angle values less than 90° were measured PVA/CHT-4/MMT-4/ Oilclove2, PVA/CHT-4/NC- 4/Oilclove2 hydrogels. According to FT-IR, SEM, XRD, Contact angle, and swelling test results, PVA/CHT/Clay/Oil hydrogel content was determined as 25 µL of clove oil and 72.7% PVA (400 mg), 9.1% CHT (50 mg), 18.2% Clay (100 mg).

Abstractπ-Conjugated azomethine ligands differing in the naphthalene or phenylmethane-centered core structure and their divalent cobalt, nickel, copper, and zinc metal complexes were prepared and well-characterized by spectral analyses in solid state. Magnetic natures of the complexes were determined by magnetic susceptibility measurements in solid-state. Their remarkable photophysical characteristics were recorded by Uv–vis and Fluorescence spectroscopic techniques. At their excitation wavelenght of 265 nm, all molecules exhibited triple fluorescence emission bands with promising intensities above 673 nm in near infra-red region. Antibacterial and antibiofilm activities of the π-conjugated azomethines are promising for potential applications in medical and healthcare settings. Hence, the antibacterial/antibiofilm activity of the π-conjugated azomethine ligands and their metal complexes against some clinically important bacteria namely Staphylococcus aureus (MSSA), Methicillin-resistant Staphylococcus aureus (MRSA), Staphylococcus epidermidis, Escherichia coli, Pseudomonas aeruginosa and Proteus mirabilis was investigated, and the obtained results have shown that the ligands and complexes had a remarkable antibacterial effect, especially on Proteus mirabilis. Metal complexes have been found to have a significant inhibitory effect on biofilm formation by MRSA, MSSA, and P. mirabilis compared to ligands. The copper (II) complex of ligand-2 showed the highest inhibition percentage, significantly reducing biofilm formation for MRSA and MSSA. Furthermore, cobalt (II) complexes of the ligands selectively inhibited the growth of the opportunistic pathogen P. mirabilis biofilms, indicating that metal complexes might be a good choice for future antibiofilm studies.
