Magnetoreception

Magnetoreception

Magnetoreception is the ability of certain organisms to detect and perceive a magnetic field, which allows them to determine direction, altitude, or location. Cryptochromes are believed to be the potential magnetosensor responsible for animal magnetoreception. This sense is present in various organisms such as bacteria, arthropods, mollusks, and some vertebrates, but not in humans.From: st Century Nanoscience – A Handbook [2020], Single-molecule spectroscopy of radical pairs, a theoretical treatment and experimental considerations [2019], Our Animal Connection [2019]

In this chapter, we will discuss mainly how electromagnetic phenomena generated from atmospheric activity relate to biological systems. In addition, we will focus on electroreception and magnetoreception. They have a connection with the change of electromagnetic fields in nature. Electroreception is the ability to detect external electric field. Magnetoreception is the ability to sense changes in a magnetic field to perceive direction, position, and navigation.

Alternatively, there is a great possibility that the molecular dynamics can be quantitatively probed by observing the decoherence processes of radical pairs. Such an approach would help understanding complicated electron transfer mechanisms in biological and artificial systems. In the future, the mechanism of avian magnetoreception would be clarified by studying controlling mechanisms of the spin decoherence in avian cryptochrome with detailed analysis of experimental MFE by MD-assisted spin dynamics simulations. In the case of electron−hole pairs in organic semiconductor thin films, diffusion modelling based on the microscopic structures of the disordered organic solids and its combination with spin dynamics simulations would clarify the molecular-level mechanisms of charge extinction (mainly recombination) from electrically and/or optically detected MFE. Such studies would offer important feedback to development and engineering of these future materials.
