Abstract

Electrical Cell-Substrate Impedance Sensing is a powerful tool for monitoring real time cells properties such as adhesion, mobility and cytotoxicity. In this study, a silver/silver chloride screen-printed impedance biosensor was developed to characterize A549 lung carcinoma cells growth in the presence of collagen I, Bovine. Collagen acts as an extracellular matrix (ECM) for A549 and promotes cell attachment. The sensor was incorporated with a culture well which was fabricated from polydimethylsiloxane (PDMS). A549 cells were cultured in the chambers and impedance measurements were taken at 12 hours intervals for 120 hours. Cell Index (CI) were calculated from the impedance data and plotted in comparison with growth profile of the cells in T-flasks for validation of the sen- sor’s functionality. A549 cells were also treated with anti- tumor drug; Paclitaxel and its response were monitored over 5 days. Experimental results show significant change in CI dur- ing growth and death after exposure to Taxol, indicating that tumor growth was inhibited in the presence of Taxol.
