Probing spin effects in phycocyanin using Janus-like ferromagnetic microparticles.

In an era of interdisciplinary scientific research, new methodologies are necessary to simultaneously advance several fields of study. One such case involves the measurement of electron spin effects on biological systems. While magnetic effects are well known in biology, recent years have shown a surge in published evidence isolating the dependence on spin, rather than magnetic field, in biological contexts.

Ultrafast Coherent Delocalization Revealed in Multilayer QDs under a Chiral Potential.

In recent years, it was found that current passing through chiral molecules exhibits spin preference, an effect known as Chiral Induced Spin Selectivity (CISS). The effect also enables the reduction of scattering and therefore enhances delocalization. As a result, the delocalization of an exciton generated in the dots is not symmetric and relates to the electronic and hole excited spins.

Spin-Exciton Delocalization Enhancement in Multilayer Chiral Linker/Quantum Dot Structures.

The control of complex devices on the nanoscale is challenging. The development of nanoparticles, such as quantum dots, that serve as "artificial atoms" enables the manipulation of energy levels at the nanoscale. Using quantum dots and wet chemistry, multilayer structures with unique coupling properties can be realized.
