Evidence for AC Fields from Living Biological Cells

Peculiarities of live cells' interaction with micro- and nanoparticles

“…Pohl, published several papers about the interactions of live cells with dispersed particles [13][14][15][16][17]. The main purpose of these studies was to verify the hypothesis suggested in late 1960s by H. Frohlich who had proposed that live cells emit an AC electric field [18,19].…”

“…The screening would make it practically impossible to generate a low-frequency electric field by moving charges inside the cell (see discussion on page 54 in [17]). In the later review [16], Pohl mentioned that frequencies were on a MHz scale.…”

“…1a). Pohl stated clearly that these phenomena was observed only for live cells [16]: "…only random patterns develop about dead cells…".…”

“…Pohl and his group at the Massachusetts Institute of Technology (MIT) [13][14][15][16][17]. They monitored the motion of small particles in the vicinity of biological cells to verify Frohlich's hypothesis [18,19] that implied that biological cells generated an AC electric field.…”
