We report label-free imaging of cell status by using electric-double-layer modulation imaging (EDLMI) technique which visualizes spatial distribution of electric double layer formed at semiconductor-electrolyte solution interface. The method utilizes the phenomenon that charge density of electric double layer responses sensitively to permittivity of adsorbed biological material. Here we report the example of cell status visualization by the EDLMI technique.
