Dear Colleagues,

Metal nanoparticles (e.g. gold and silver nanoparticles) have long been utilized for various types of chemical and/or biological sensing applications. At the same time, much of the knowledge being gained for manipulating nanoparticle structure or composition has focused on multimetallic type nanoparticles. Such systems can display multiple properties arising from the individual components, but it is the observation of synergistic phenomena that is the most intriguing.

By taking advantage of such synergestic phenomena in multimetallic nanoparticles including alloy, core-shell, and other heterostructures, one can enhance the sensing propeties when these multimetallic nanoparticles are used as sensing probes.

This special issue aims to cover all various aspects, such as (but not limited to) novel multimetallic nanoparticles as sensing probes, new insights in synergestic phenomena in terms of sensing properties, and sensing applications of multimetallic nanoparticles.

Abstract: Bi-metallic nanomaterials have the ability to exhibit multifunctional characteristics as well as novel properties. As a result, it is being applied to a variety of applications, including in biological and chemical sensing, catalysis, high density magneto-optical recording and in energy harvesting. Here we will review the current state-of-art in the design, synthesis, processing, characterization and functionality of such materials, with particular emphasis on sensing by optical, plasmonic and magnetically-driven approaches.
