Purified reovirus type 3 (strain Dearing) was treated with monoclonal anti-?l antibody conjugated to ferritin and examined in the electron microscope. Virion associated ferritin molecules corresponding to locations of the ?l protein were observed. Electron microsocpy of thin sections of these preparations revealed that ferritin conjugates were localized at the vertices of the viral icosahe...

A new folate-conjugated gold nanoparticle (AuNP) has been designed to selectively target the folate receptor that is overexpressed on the surface of tumoral cells. For this purpose, we made 4-aminothiophenol, as a bifunctional linker to react with HAuCl4 in the presence of sodium borohydride and it was binded to the AuNP surface through its thiol group. Then, we conjugated amino-terminated nano...

We show that diradicaloid helical conjugated molecules can display strong through-space bonding interactions. These interactions are analogous to π-stacking pancake bonding widely observed for dimers and other aggregates of stable π-conjugated radicals. We show that these multicenter interactions can have a significant stabilizing effect, but they depend in subtle ways on the specific overlap a...

Abstract Self-organization in ? -conjugated polymers gives rise to a highly ordered lamellar structure, which inter-chain stacking spontaneously forms two-dimensional conjugated sheets. This multi-layer stacked nature of semicrystalline allows the inclusion various functional molecules. In particular, redox-triggered ion-intercalation is an ideal system for molecular doping, extremely high char...

Electron transport properties through single conjugated molecules sandwiched between two nonsuperconducting electrodes are studied by the use of Green’s function technique. Based on the tightbinding model, we do parametric calculations to characterize the electron transport through such molecular bridges. The electron transport properties are significantly influenced by (a) the existence of loc...

Molecular electronics describes a field that seeks to implement electronic components made of molecular building blocks. To date, few studies have used conjugated polymers in molecular junctions despite the fact that they potentially transport charge more efficiently than the extensively investigated small-molecular systems. Here we report a novel type of molecular tunnelling junction exploring...

Inside back cover image: Crystal structure of π-conjugated small molecules and polymers is fundamentally critical to understand the multilevel microstructures. However, determining crystal conjugated remains a significant challenge. Jian Pei coworkers build possible structures eight typical polymers, covering several widely used molecular segments in organic optoelectronics. These are modeled b...
