Spin chemistry deals with the effects of electron and nuclear spins on the rates and yields of chemical reactions. From its many applications, we are particularly interested in possible biological effects of extremely low frequency and radiofrequency electromagnetic fields, the mechanisms by which animals can sense the Earth's magnetic field for orientation and navigation, and the possibility of manipulating radical lifetimes so as to control the outcome of their reactions.

Chemical compass
In the enchanting world of nature's mysteries, many migratory animals possess a remarkable compass-like sense known as "magnetoreception." This extraordinary ability enables them to embark on epic journeys guided by the Earth's magnetic field. Imagine songbirds taking to the skies, their internal compasses attuned… Read more
Spin relaxation in proteins
Proteins are not static structures but are constantly in motion due to thermal fluctuations. These motions induce spin relaxation in radical pairs formed within the proteins. A radical pair, once generated, enters an entangled quantum state, like the singlet state, where there is a substantial coherence between… Read more
Spin relaxation in membranes
Our research delves into the fascinating realm of radicalized lipids within cell membranes, a phenomenon linked to cancer initiation. Specifically, cancer cells exhibit a higher concentration of radicalized lipids than normal cells, making quantifying these radicals a potential marker for the presence of cancer… Read more
RF effects on radical pair mechanics
The radical pair mechanism, a fascinating concept in the world of spin chemistry, is thought to play a vital role in how birds navigate using Earth's magnetic field. This mechanism is susceptible to even the gentlest magnetic fields. Intriguingly, there is evidence to suggest that radio-frequency (RF) fields have… Read more
Photo-CIDNP in complex systems
Are you familiar with Chemically Induced Dynamic Nuclear Polarization (CIDNP)? It denotes a remarkable phenomenon in which the nuclear spins of atomic nuclei undergo specific orientation changes during chemical reactions. Analogous to partners unexpectedly aligning on a dance floor due to their chemistry, CIDNP… Read more
