Mechanism of ion transport across bilayer membranes

Introduction The facilitated transport of ions and polar molecules across biological membranes is essential for normal cell function and is also a major objective in the rapidly growing field of drug delivery. Researchers strive to simulate naturally occurring channel-forming proteins or carrier molecules. The resultant compounds may utilize endogenous peptide sequences or may be novel organic ...

Ion transport through biological channels

The transport of ions across single-molecule protein nanochannels is important both in the biological context and in proposed nanotechnological applications. Here we discuss these systems from the perspective of non-equilibrium physics, and in particular, whether the concepts underlying the physics of diffusive and electrokinetic transport can be employed to predict and understand these systems...

Simulation study of the transport properties of ions through ion channels serving as primary components of a nanobiosensor

Ion channels are naturally occurring pores through the proteins that regulate the passage of ions and thus maintain the concentration of ions inside and outside the cell. The ion channels control many physiological functions and they can show selectivity for a specific ion. Ion channels are mostly observed in nerve cells and muscle cells. The influx of ions into cells can be regulated by a gate...
