The electrochemical study of electron transport between Au electrodes and the redox molecule Os[(bpy)2(PyCH2 NH2CO-]ClO4 tethered to molecular linkers of different length (1.3 to 2.9 nm) to Au surfaces has shown an exponential decay of the rate const

In contrast with the case of thiols, molecular level information regarding the binding of carbon to metals is very scarce. Motivated by the growing interest in the grafting of conducting surfaces and seeking a rationale to explain the differences in

hemically modified electrodes by the osmium complex [Os(bpy)2Clpy−X]+PF−6 tethered to Au surfaces by (1) reaction of cysteamine with the aldehyde (X=CHO), (2) mercapto alkanoic acid reaction with amine [X=(CH2)2NH2], and (3) reduction of the diaz
Experimental evidence of the variation in redox potential of osmium pyridine complexes tethered to a Au surface by thiol or diazonium chemistry at different ionic concentration and electrolyte pH is described. The interplay between the charged redox

The main polysaccharides from the red seaweed Lithothamnion heterocladum share the general characteristics of corallinans (agar-like xylogalactans), even though this seaweed is crustose, whereas those previously studied in detail were articulated sea

We describe a general framework to design nanobiosensors based on a wired enzyme coupled to a redox molecule and integrated with SERS Au core-shell nanoparticles and ordered nanocavities. The response of the proposed sensor is based on the different
