The emerging field of using titanium dioxide (TiO 2 )-based photosensitizers for enhancing photocatalytic removal thiazine dyes such as methylene blue (MB) from water has long been recognized its exceptional properties, making it an attractive material environmental remediation and energy conversion. However, wide bandgap limits responsiveness to visible light. As such, the utilization TiO -based dyes, presents a promising avenue diverse applications. In addressing dual challenges pollution harnessing sustainable sources, this review focuses on their subsequent application materials. Thiazine ubiquitous in industrial effluents, pose concerns due persistence potential toxicity. Conversely, innovative approach involves employing materials photocatalysts, utilizing unique properties enhance light absorption. Studies have shown that beyond conventional role colorants, they can serve effective when coupled with . This tandem not only facilitates elimination MB, but also augments improvement performance synergy between dye sensitizers enhances overall efficiency processes like degradation splitting. Dye sensitizers, acting absorbers, efficiently transfer , thereby promoting electron generating reactive oxygen species (ROS). These ROS, turn, initiate chemical reactions, rendering valuable applications wastewater treatment, solar conversion, remediation. is crucial acknowledge drawbacks associated including toxicity non-biodegradability. Consequently, careful consideration must be given disposal. Therefore, manuscript delves into comprehensive exploration photosensitizers, shedding efficacy various removal.

Published: July 20, 2023

Gold nanoparticles (AuNPs) and carbon nanotubes (CNTs) are increasingly being investigated for cancer management due to their physicochemical properties, low toxicity, biocompatibility. This study used an eco-friendly technique (laser synthesis) fabricate AuNP Au/CNT nanocomposites. AuNPs, Au/CNTs, CNTs were tested as potential nanotherapeutics on colorectal carcinoma cells (HCT-116) cervical (HeLa) using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. In addition, the non-cancer embryonic kidney HEK-293 taken control in study. The cell viability assay demonstrated significant reduction population post 48 h treatments of Au/CNTs. average viabilities HCT-116 50.62%, 65.88%, 93.55%, HeLa cells, 50.88%, 66.51%, 91.73%. 50.44%, 65.80%, 93.20%. Both AuNPs Au/CNTs showed higher toxicity death compared with CNT nanomaterials. treatment strong inhibitory action cells. However, did not significantly decrease there was only minor decrease. normal also viability, but produce shows that simplified synthesis like laser preparation high-purity nanomaterials has good efficacy possible future therapy minimal toxicity.
