The treatment of dye-contaminated wastewater is essential for mitigating environmental and health risks. In this study, we developed a novel nanocomposite, TiO₂-incorporated graphene oxide (TiO₂@GOn), aimed at enhancing the photocatalytic degradation of neutral red dye, which served as the target analyte. The photocatalysis technique was employed, leveraging the excitation of TiO₂ under UV light to generate reactive oxygen spe...

Simple, portable, and low-cost paper-based sensors are alternative devices that have the potential to replace high-cost sensing technologies. The compatibility of the paper base biosensors for both chemical and biochemical accentuates its feasibility for application in clinical diagnosis, environmental monitoring, and food quality monitoring. High concentration of copper in blood serum and urine is associated with diseases lik...
