Abstract
A method of fabricating an array on nanoparticles includes forming a solution containing a material precursor and an electrolyte. The solution is laded into a pipet and a wire is inserted into the solution. The pipet is brought into contact with a substrate and an electrical bias is applied between the substrate and the wire. A nanoparticle is formed via electrodeposition. The steps of bring a pipet into contact with the substrate, applying an electrical bias, and forming a nanoparticle across an array of contact points to create the array of nanoparticles. The substrate is rinsed with a solvent to remove residual electrolytes.
