For detection of gases and vapors in complex backgrounds, “classic” analytical instruments are an unavoidable alternative to existing sensors. Recently a new generation of sensors, known as multivariable sensors, emerged with a fundamentally different perspective for sensing to eliminate limitations of existing sensors. In multivariable sensors, a sensing material is designed to have diverse responses to different gases and vapors and is coupled to a multivariable transducer that provides independent outputs to recognize these diverse responses. Data analytics tools provide rejection of interferences and multi-analyte quantitation. This review critically analyses advances of multivariable sensors based on ligand-functionalized metal nanoparticles also known as monolayer-protected nanoparticles (MPNs). These MPN sensing materials distinctively stand out from other sensing materials for multivariable sensors due to their diversity of gas- and vapor-response mechanisms as provided by organic and biological ligands, applicability of these sensing materials for broad classes of gas-phase compounds such as condensable vapors and non-condensable gases, and for several principles of signal transduction in multivariable sensors that result in non-resonant and resonant electrical sensors as well as material- and structure-based photonic sensors. Such features should allow MPN multivariable sensors to be an attractive high value addition to existing analytical instrumentation.

迈向高价值传感：多变量气体和蒸汽传感器中的单层保护金属纳米颗粒

为了检测复杂背景下的气体和蒸气，“经典”分析仪器是现有传感器不可避免的替代产品。最近，新一代的传感器（称为多变量传感器）以根本不同的视角出现，从而消除了现有传感器的局限性。在多变量传感器中，传感材料被设计为对不同的气体和蒸气具有不同的响应，并耦合到提供独立输出以识别这些不同响应的多变量换能器。数据分析工具可消除干扰并进行多分析物定量分析。这篇评论严格分析了基于配体官能化的金属纳米颗粒（也称为单层保护纳米颗粒（MPN））的多变量传感器的进展。这些MPN传感材料由于有机和生物配体所提供的气体和蒸汽响应机制的多样性而在多变量传感器的其他传感材料中脱颖而出，这些传感材料适用于各种类型的气相化合物，例如可冷凝的蒸汽和不可凝气体，以及用于多变量传感器中信号转换的几种原理，从而导致产生非共振和共振电传感器以及基于材料和结构的光子传感器。此类功能应使MPN多变量传感器成为现有分析仪器的诱人的高附加值产品。这些感测材料适用于各种气相化合物，例如可冷凝的蒸气和不可冷凝的气体，以及多变量传感器中信号转导的几种原理，这些原理会导致非共振和共振电传感器以及材料和结构基于光子的传感器。此类功能应使MPN多变量传感器成为现有分析仪器的诱人的高附加值产品。这些感测材料适用于各种气相化合物，例如可冷凝的蒸气和不可冷凝的气体，以及多变量传感器中信号转导的几种原理，这些原理会导致非共振和共振电传感器以及材料和结构基于光子的传感器。此类功能应使MPN多变量传感器成为现有分析仪器的诱人的高附加值产品。
