One possible explanation for magnetosensing in biology, such as avian magnetoreception, is based on the spin dynamics of certain chemical reactions that involve radical pairs.Radical pairs have been suggested to also play a role Diindolylmethane (DIM) in anesthesia, hyperactivity, neurogenesis, circadian clock rhythm, microtubule assembly, etc.It thus seems critical to probe the credibility of such models.One way to do so is through isotope effects with different nuclear spins.Here we briefly review the papers involving spin-related isotope effects in biology.
We suggest studying isotope effects can be an interesting avenue Motion Sensor for quantum biology.
