Chemical and biological sensing are crucial tools in science and technology. Plasmonic nanoparticles offer a virtually limitless number of photons for sensing applications, which can be available for visual detection over long periods. Moreover, cellulosic materials, such as paper, represent a versatile building block for implementation of simple, yet valuable, microfluidic analytical devices. This mini review outlines the basic theory of nanoplasmonics and the usability of paper as a nanoplasmonic substrate exploiting its features as a (bio)sensing platform based on different mechanisms depending on localized surface plasmon resonance response. Progress, current trends, challenges and opportunities are also underscored. It is intended for general researchers and technologists who are new to the topic as well as specialist/experts in the field.
化学和生物传感是科学技术中的关键工具。等离子体纳米颗粒为传感应用提供了几乎无限数量的光子,可用于长期的视觉检测。此外,纤维素材料,如纸张,是实现简单但有价值的微流控分析设备的通用构建模块。本综述概述了纳米等离子体学的基本理论,以及纸张作为纳米等离子体基底的可用性,利用其作为基于局域表面等离子体共振响应的不同机制的(生物)传感平台的特性。还强调了进展、当前趋势、挑战和机遇。它面向该主题的新手普通研究人员和技术人员以及该领域的专家。
