Abstract :
Dielectrophoresis is often used for characterisation of bioparticles on the cellular and subcellular scale. Dielectrophoretic crossover analysis enables the determination of biophysical properties of such particles. The DEP properties of colloidal particles (less than one micrometre diameter) are strongly dependent on the surface particle conductivity. Recent work has demonstrated how the effective conductivity of small latex spheres contains components due to both Stern layer and diffuse double layer. Here we demonstrate that this model can also be used to account for the DEP behaviour of virus particles such as Herpes Simplex (HSV-1)
