This laboratory study exposed a Geobacter sulfurreducens-inoculated bioelectrochemical system to 0–128 Gauss extremely low-frequency electromagnetic fields. The authors report increased and oscillatory metabolic current under ELF-EMF exposure, with dose-dependent effects and a linear relationship between oscillation…

This in vitro study used voltage clamp recordings of single OmpF porin channels in an artificial bilayer to test effects of UHF EMF (910–990 MHz). The authors report frequency-dependent changes in channel gating, with increased gating frequency and voltage sensitivity and a maximum effect at 930 MHz. Conductance was…

This experimental study examined whether strong electric fields used for electrophoretic actuation of charged water-in-oil droplets affect living cells inside the droplets. Using Trypan blue and cell growth tests across electric field strengths of 1–3 kV/cm and varying actuation times, the authors report no…

This paper describes an exposure and microscopy system designed to continuously observe living cells during exposure to modulated RF-EMF similar to mobile phone signals. Using protocols where the same cells serve as controls before and after exposure, the system was validated with endocytosis measurements. Under 900…

This paper describes an aerodynamically assisted bio-jetting technique that processes living cells/organisms using differential pressure rather than an electric field. The authors report an operational window for stable jetting and near-monodispersed cell-bearing droplets. Cell viability after jetting was evaluated…
