Template electrodeposition of catalytic nanomotors.
The combination of nanomaterials with electrode materials has opened new horizons in electroanalytical chemistry, and in electrochemistry in general. Over the past two decades we have witnessed an enormous activity aimed at designing new electrochemical devices based on nanoparticles, nanotubes or nanowires, and towards the use of electrochemical routes--particularly template-assisted electrode...
متن کاملCatalytic nanomotors: autonomous movement of striped nanorods.
Rod-shaped particles, 370 nm in diameter and consisting of 1 microm long Pt and Au segments, move autonomously in aqueous hydrogen peroxide solutions by catalyzing the formation of oxygen at the Pt end. In 2-3% hydrogen peroxide solution, these rods move predominantly along their axis in the direction of the Pt end at speeds of up to 10 body lengths per second. The dimensions of the rods and th...
متن کاملPhysical channel characterization for medium-range nanonetworks using catalytic nanomotors
Molecular communication is a promising paradigm to implement nanonetworks, the interconnection of nanomachines. Catalytic nanomotors constitute one of the techniques that have been proposed for medium-range molecular communications. This paper presents a physical channel characterization that shows how nanomachines communicate using catalytic nanomotors as information carriers. Quantitative res...
متن کاملCatalytic nanomotors: self-propelled sphere dimers.
Experimental and theoretical studies of the self-propelled motional dynamics of a new genre of catalytic sphere dimer, which comprises a non-catalytic silica sphere connected to a catalytic platinum sphere, are reported for the first time. Using aqueous hydrogen peroxide as the fuel to effect catalytic propulsion of the sphere dimers, both quasi-linear and quasi-circular trajectories are observ...
متن کاملMotion-driven sensing and biosensing using electrochemically propelled nanomotors.
Electrochemically-propelled nanomotors offer considerable promise for developing new and novel bioanalytical and biosensing strategies based on the direct isolation of target biomolecules or changes in their movement in the presence of target analytes. For example, receptor-functionalized nanomotors offer direct and rapid target isolation from raw biological samples without preparatory and wash...
