Abstract
Localized surface plasmon resonance (LSPR) is an optical phenomenon associated with noble metal nanostructures. The resonances result in sharp spectral absorption peaks as well as enhanced local electromagnetic fields, which have been widely used in chemical and biological sensing. Over the past decade, as label-free analytical method, LSPR sensors have gained considerable interest and undergone rapid development. In addition to conventional refractive-index sensing through resonant wavelength shift, molecular sensing by colorimetry and imaging techniques have also been developed. Moreover, the LSPR sensors have been integrated with other techniques such as micro/nano fluidics and artificial intelligence (AI) to enhance their functionality and performances. In this work, we provide an overview of the recent advancement in LSPR sensors technology, including refractive-index, colorimetric, and imaging-based sensors, as well as the incorporation of new technologies like AI.
期刊介绍：
The journal aims to publish papers at the forefront of nanoscale science and technology and especially those of an interdisciplinary nature. Here, nanotechnology is taken to include the ability to individually address, control, and modify structures, materials and devices with nanometre precision, and the synthesis of such structures into systems of micro- and macroscopic dimensions such as MEMS based devices. It encompasses the understanding of the fundamental physics, chemistry, biology and technology of nanometre-scale objects and how such objects can be used in the areas of computation, sensors, nanostructured materials and nano-biotechnology.
