Electric and dye coupling

Electric and Dye Coupling Between Rat Carotid Body Cells and Between These Cells and Carotid Nerve Endings... 

Semiconductor nanorods are very promising for the future development of ET-based switches controlled by an electric field. In particular, CdSe/CdS nanorods exhibit a large quantum-confined Sfark effect at the single-particle level, which enables direct control of the spectral resonance between donor and acceptor required for nanoscopic Forster-type ET in single nanorod-dye couples.The applied electrical field, in fact, allows to tune... 

In addition to the described above methods, there are computational QM-MM (quantum mechanics-classic mechanics) methods in progress of development. They allow prediction and understanding of solvatochromism and fluorescence characteristics of dyes that are situated in various molecular structures changing electrical properties on nanoscale. Their electronic transitions and according microscopic structures are calculated using QM coupled to the point charges with Coulombic potentials. It is very important that in typical QM-MM simulations, no dielectric constant is involved Orientational dielectric effects come naturally from reorientation and translation of the elements of the system on the pathway of attaining the equilibrium. Dynamics of such complex systems as proteins embedded in natural environment may be revealed with femtosecond time resolution. In more detail, this topic is analyzed in this volume [76].
