Active matter as the underpinning agency for extraordinary sensitivity of biological membranes to electric fields

Research RF Safe Research Library Jan 1, 2025

This biophysics paper presents a nonequilibrium (active matter) statistical mechanics model for electromechanical biological membranes. It argues that energy-driven activity in membranes could enable detection of electric fields far below equilibrium thermal-noise limits, and reports that the model can reproduce…

Thermodynamic Considerations on the Biophysical Interaction between Low-Energy Electromagnetic Fields and Biosystems.

Research RF Safe Research Library Jan 1, 2024

This paper presents a thermodynamic model intended to explain how extremely low-frequency electromagnetic fields (ELF-EMFs) may interact with cells. The authors propose that ELF-EMFs directly interfere with the cellular membrane, producing biological responses linked to energy conversion and changes in flows across…

Weak electric fields detectability in a noisy neural network.

Research RF Safe Research Library Jan 1, 2017

This modeling study examines how a noisy spiking neural network detects a weak applied electric field using an Izhikevich neuron framework with excitatory/inhibitory neurons and conduction delays. The authors report stochastic resonance driven by white noise that enhances detectability, and that this effect largely…

Molecular dynamics study of response of liquid N,N-dimethylformamide to externally applied electric field using a polarizable force field.

Research RF Safe Research Library Jan 1, 2014

This molecular dynamics simulation study examined liquid N,N-dimethylformamide exposed to uniform external electric fields from 0.001 to 1 V/nm using an extended AMOEBA polarizable force field. The authors report that fields above 0.01 V/nm significantly altered the liquid’s structure and a range of molecular and…

Three-dimensional dynamics of a particle with a finite energy of magnetic anisotropy in a rotating magnetic field.

Research RF Safe Research Library Jan 1, 2013

This paper presents a theoretical model of a single ferromagnetic particle with finite coupling between its magnetic moment and particle body in a rotating magnetic field. It describes synchronous and asynchronous motion regimes, including planar motion at low frequencies and a precession regime at high frequencies,…

Biological proton pumping in an oscillating electric field.

Research RF Safe Research Library Jan 1, 2009

This paper models biological proton pumping in cytochrome c oxidase under an applied oscillating electric field. The authors report that proton pumping efficiency and steady-state electronic currents vary significantly with the field’s frequency and amplitude. A spectral analysis is described as supporting dominant…
