Background: Staphylococcal protein A (SPA) is a cell wall component of Staphylococcus aureus that binds to different IgG subclasses of human and several animal species. This bacterial protein can be used as an antibody detector in various immunological assays or as an isolation reagent for the purification of antibody molecules via immuno-chromatography procedures.Objectives: Molecular cl...

the research in new organic π-conjugated molecules with specific properties has become one of the most interesting topics in fields of materials chemistry. these materials are promising for optoelectronic device technology such as solar cells. on the other hand, the use of low band gap materials is a viable method for better harvesting of the solar spectrum and increasing its efficiency. the co...

Conduction of electro-migration gap junctions coated with various organic molecules is studied to expose the prevalence of different transport processes. The principal comparison made here is between molecules with conjugated versus non-conjugated backbones. Coulomb blockade (CB) is observed in all junctions, including bare junctions and those with non-conjugated molecules, but at significantly...

We present an interesting consequence of the differences between cross-conjugated and linearly conjugated molecules: the breakdown of conventional understanding of trends in molecular electron transfer. Interference effects are dominant in cross-conjugated molecules with unusual results: long molecules may have faster rates of electron transfer than short molecules, saturated molecules may have...

We study coherent phonon transport through organic, π-conjugated molecules. Using first principles calculations and Green's function methods, we find that the phonon transmission function in cross-conjugated molecules, like meta-connected benzene, exhibits destructive quantum interference features very analogous to those observed theoretically and experimentally for electron transport in simila...
