摘要

Nanowires are critically important building blocks of nanotechnology. Much of the excitement on nanowires arisen from with the ability to introduce different chemical functions through the use of multiple segments along these nanoscale objects. The multifunctionality of such multisegment nanowires allows these nanostructures to perform several tasks simultaneously. This short review covers recently developed protocols based on adaptive multifunctional magnetic nanowires for controlling on-demand the operation of electrochemical sensors and microchip devices and for triggering and modulating electrocatalytic and bioelectrocatalytic processes. Magnetic stimulus can be used for activating reversibly various bioelectrocatalytic and electrocatalytic processes through controlled surface orientation of multifunctional magnetic nanowires. The ability to use adaptive nanowires to switch electrochemical devices between active and passive states will be illustrated for protecting electrochemical sensors against surface fouling and for controlling amperometric detection for separation microchips. Such nanowire-based adaptive operation should lead to the next-generation of 'smart' self-activated analytical and bioelectronic devices.
