Electrochemical template synthesis of multisegment nanowires: fabrication and protein functionalization.

Multisegment nanowires represent a unique platform for engineering multifunctional nanoparticles for a wide range of applications. For example, the optical and magnetic properties of nanowires can be tailored by modifying the size, shape, and composition of each segment. Similarly, surface modification can be used to tailor chemical and biological properties. In this article, we report on recent work on electrochemical template synthesis of nanogap electrodes, the fabrication of multisegment nanowires with embedded catalysts, and the selective functionalization of multisegment nanowires with proteins.
