First-Principles Approach to Dielectric Dispersion of Nonspherical Cells (Completed) There is an increasing evidence that the study of dielectric properties of cells in radio-frequencies leads to new applications in biotechnology. Recent dielectric measurements revealed that the dielectric dispersion spectrum of rod-like cells in a suspension depends strongly on the cell length. However, no model calculations can explain such experimental data satisfactorily, which indicates that new theories are required. In this project, we will develop a first-principles approach for rod-like cells which enables us to calculate the spectral representation of cell suspension needed for the description of the dielectric dispersion data. The project will generate an appropriate theory for the explanation and prediction of dielectric properties of cells in radiofrequencies. Such a theory will be a powerful tool in the development of biotechnology.
