The following study evaluates the toxicological profile of a selected metal-organic framework utilizing electric cell-substrate impedance sensing (ECIS), a real-time, high-throughput screening technique.
My research aims to evaluate changes in human lung epithelial cells'behavior upon exposure to metal organic framework, hybrids formed by combining metal ions in organic linkers in organic solvents. This research demonstrated that the physical and chemical composition of metal organic frameworks, as well as their cellular exposure ratios, affects the behavior of human lung epithelial cells in a time and dose-dependent manner. This can be recorded in a high throughput in real time fashion.
Our research helps to evaluate, understand the mechanisms of toxicity of metal organic frameworks upon exposure to cellular systems. The current method allows continuous cell monitoring in a real time and in high throughput manner. Additionally, this method does not rely on any external reagents, and thus it reduces any possible interference they could have with the frameworks used for exposure.
Our laboratory will continue to focus on understanding and evaluating the mechanisms of toxicity associated with nanomaterials exposures, as well as using such information to synthesize new and safe systems that could be implemented in biomedical applications at minimum risks to the user or the environment.
