In this study, we determined the LD(50) (50% lethal dose) for cell death, and the ED(50) (50% of cell population staining positive) for propidium (Pr) iodide uptake, and phosphatidylserine (PS) externalization for several commonly studied cell lines (HeLa, Jurkat, U937, CHO-K1, and GH3) exposed to 10-ns electric pulses (EP). We found that the LD(50) varied(More)
THz spectroscopy is an emerging technique for studying the dynamics and interactions of cells and biomolecules, but many practical challenges still remain in experimental studies. We present a prototype of simple and inexpensive cell-trapping microfluidic chip for THz spectroscopic study of live cells. Cells are transported, trapped and concentrated into(More)
The gene expression kinetics for human cells exposed to hyperthermic stress are not well characterized. In this study, we identified and characterized the genes that are differentially expressed in human epidermal keratinocyte (HEK) cells exposed to hyperthermic stress. In order to obtain temporal gene expression kinetics, we exposed HEK cells to a heat(More)
The goal of this special issue is to present original contributions in the area of terahertz imaging and spectroscopy relevant to biomedicine. Authors are invited to submit paper contributions including (but not limited to) the following topics:  Terahertz spectroscopy of proteins and other bio-molecules  Terahertz imaging of biological tissues (More)
