The dielectric behaviour of single-shell spherical cells with a dielectric anisotropy in the shell

摘要: Recent experiments on cells treated with hydrophobic ions showed that the mobile charges adsorbed to plasma membrane contributed significantly low-frequency dielectric behaviour of cells. Due different transport properties along radial and tangential directions within membrane, there is a anisotropy in membrane. In this work, we adopted single-shell spherical cell model an intrinsic dispersion which can be isotropic or anisotropic. We developed spectral representation (DDSR) expressed Clausius–Mossotti factor terms series sub-dispersions. This enables us assess effects permittivities conductivities further assessed spectrum DDSR. To end, interpreted results as change strength, well shift characteristic frequency. Moreover, changes are indeed small weak-anisotropy expansion justified.
