Nanoparticle Arrays on Surfaces for Electronic, Optical, and Sensor Applications

TLDR

Nanoparticles, whose electronic and optical properties arise from their nanometer dimensions, are increasingly studied for nanoengineering surfaces and creating functional interfaces, with recent efforts focused on organizing them on substrates. This review surveys research that has enabled sensing, electronic, optoelectronic, and photoelectronic interfaces through nanoparticle arrays, while also covering synthesis and characterization methods. The authors compile and discuss synthesis protocols, characterization techniques, and surface organization strategies for nanoparticle arrays that underpin these functional interfaces.

Abstract

Particles in the nanometer size range are attracting increasing attention with the growth of interest in nanotechnological disciplines. Nanoparticles display fascinating electronic and optical properties as a consequence of their dimensions and they may be easily synthesized from a wide range of materials. The dimensions of these particles makes them ideal candidates for the nanoengineering of surfaces and the fabrication of functional nanostructures. In the last five years, much effort has been expended on their organization on surfaces for the construction of functional interfaces. In this review, we address the research that has led to numerous sensing, electronic, optoelectronic, and photoelectronic interfaces, and also take time to cover the synthesis and characterization of nanoparticles and nanoparticle arrays.
