| Abstract | ||||
| Instances of cadmium poisoning have been documented across various regions worldwide, presenting a significant global health concern with the potential to impact multiple organs and, in severe cases, result in fatalities on an annual basis. Prolonged exposure to cadmium, whether through inhalation of air, consumption of contaminated water and food, or contact with polluted soil, is associated with carcinogenic effects and systemic toxicity affecting various organ systems. These include but are not limited to the skeletal, urinary, reproductive, cardiovascular, central and peripheral nervous, and respiratory systems. Nano sensors designed for Cd detection leverage the unique properties of nanomaterials, such as quantum dots, nanotubes, and nanoparticles, to enhance sensitivity and selectivity. These nanoscale devices not only offer improved detection limits but also provide the potential for real-time, on-site monitoring, overcoming the limitations of traditional analytical methods. This pioneering approach has resulted in the development of an innovative nanoscale copper sensor designed specifically for the detection and identification of cadmium. The comprehensive characterization of the nano copper Schiff base complex involved a systematic application of advanced analytical methodologies. Techniques such as scanning electron microscopy (SEM), atomic force microscopy (AFM), Fourier-transform infrared spectroscopy (FTIR), dynamic light scattering (DLS), zeta potential analysis, thermogravimetric analysis (TGA/DTG), and BET surface area and pore size determination were employed to elucidate the intricate structural and physicochemical attributes of the complex. Moreover, the utilization of a nano Schiff base copper complex has been employed as an economical, straightforward, and remarkably sensitive sensing platform using Quartz Crystal Microbalance (QCM) technology for the swift identification of cadmium. This Nano Schiff base copper complex sensor exhibits a notable capability to detect cadmium ions at extremely low concentrations, reaching levels as minimal as 1 ppm. It is imperative to highlight that a comprehensive evaluation of the cytotoxicity of the cadmium complex nanoparticles has been conducted to ensure their biocompatibility and safety. | ||||
