چکیده
Objective(s): Cadmium sulfur (CdS) is a type of quantum dot which is a unique light-emitting semiconductor nanocrystal. Quantum dots have wide applications in optoelectronics, solar cells, biology, and medicine fields.Materials and Methods: Morphological properties and structural analysis for CdS were tested by using different methods (TEM, XPS and XRD). Cortical neuron cells were used for toxicity investigations. The cells were treated with different concentrations of CdS (۱۰۰, ۱۰, ۱, ۰.۱, ۰.۰۱ µg/mL) and incubated for ۲۴ h (۵% CO۲; ۳۷°C). In vitro studies were done by examining cellular viability (MTT assay) and oxidative stress/status (TAC/TOS). Results: According to our results, the increasing concentration of CdS resulted in decreased cell viability. Total antioxidant capacity (TAC) of neurons increased following exposure to the lowest concentrations of CdS. In addition, inverse to our TAC findings, total oxidant status (TOS) was decreased following exposure to lower concentrations of CdS. Conclusion: Recently, because of advances in diagnostic and drug delivery systems ingestion rate of CdS by humans were increased. Hence, this study aimed to investigate the toxic effects of CdS on Cortex Neurons cell cultures. The production of CdS quantum dot particles was done by using the Viridibacillus arenosi K۶۴ (biosynthesis method) which provides environmentally friendly, economical, reliable, and controlled production.کلیدواژه ها
