This in vitro study exposed B16-BL6 melanoma cells to a time-varying EMF modeled after intercellular calcium-wave firing patterns. The abstract reports a 50.3% reduction in viable cells after a single 40-minute exposure and microscopy findings consistent with apoptosis and nuclear fragmentation versus control. The…

This laboratory study examined radiofrequency EMF exposure between 1 and 5.9 GHz as a method to control yeast growth relevant to food spoilage. The authors report reduced yeast viability at all tested frequencies and note that antenna-to-sample distance affected the outcome. Electron microscopy findings are described…

This study tested pulsed low-frequency electromagnetic fields (up to 10,000 Hz; max 21 mT) as a potential alternative sanitation approach for poultry drinking water systems. LF-EMF exposure was linked to variable changes in culturable bacterial counts, with direction depending on system type and some early…

This paper describes an engineering device for wireless microscopy using a mobile phone and a WiFi system. The system allows recording, displaying, and storing microscopic images from a remote end via wireless LAN. Conceptual demonstrations are reported for monitoring common objects and liver cancer cells, with…

This engineering study investigates a plasmonic nanostructure composed of a spherical metallic nanoshell with a small metallic nanoparticle (“nanoknob”) on its surface. It reports tunable plasmon resonance behavior driven by nanoshell properties and localized/enhanced electromagnetic fields near the nanoknob under…

This materials study reports that ZnO nanorod polymer hybrids can form liquid-crystalline phases and exhibit orientation switching under an applied AC electric field. The orientation reportedly changes from planar to homeotropic, analogous to switching in low-molecular liquid crystals. Dielectric measurements and…

This study characterizes the electrical potential on the surface of ~300 nm SiO2 grown on single-crystalline Si under ambient conditions using electric field microscopy. It reports an inhomogeneous surface potential with fluctuations up to ~0.4 V over ~1 µm regions. The authors propose these fluctuations could affect…

This engineering-focused study examines failure of needle-shaped specimens exposed to very high electric fields in field-ion microscopy. The authors report experiments indicating breakdown may be initiated by nanoparticles detached from a point anode. They propose a mechanism in which expanding cathode plasma…

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 in vitro study measured biophoton/chemiluminescence emission from MDCK cells after inducing reactive oxygen species with hydrogen peroxide. The authors report that photon emission increased with hydrogen peroxide dose and that photomultiplier tube measurements agreed with fluorescence microscopy observations.…
