Terahertz spectroscopy used to distinguish breast epithelial cell lines

THz spectroscopy has the potential to be used in identifying and characterizing cell types. In this study, normal 184A1 and metastatic MDA-MB-231 breast epithelial cell lines were characterized using transmission mode of THz Time-Domain Spectroscopy as they transitioned from their active to inactive state. A frequency domain scan was performed at set time intervals on both cell lines and the result showed that there is a time domain variation between the scans of the two cell lines that can be used to identify each cell type.
