Photonic and optoelectronic sensors constitute integral parts of various fields, including gas sensing, biological sensing, and molecular analysis. These concepts find application in environmental monitoring, food or medicine quality control, safety, and security. For these technologies to be competitive, they must exhibit performant properties in terms of selectivity, sensitivity, throughput, resolution, and reliability. These requirements have in common that they rely on specifically designed transducing elements, comprising structured interfaces made of specifically chosen, functional materials. The success highly depends on the ability to tune and optimize the transducing elements to the desired need. This tuning can be pursued at several levels, from material design to geometrical interface considerations, potentially leading to comprehensive, multiscale approaches. The sensor performance can be fostered by engineering the materials and the nanoscale interface structure, via either bottom–up or top–down approaches. Material engineering includes creating hybrid structures or composite materials, providing the opportunity to tune their electro-optical characteristics. The several degrees of freedom introduced by the combination of 1D to 3D structures (particles, nanowires, gratings, and photonic/plasmonic crystals) further contribute to enhanced light–matter interaction. The combination paves the way to advanced sensing concepts, including plasmonic, surface-resonance, and surface-enhanced methods. Introducing properly designed structures with multi-periodicity or deterministic aperiodicity further creates the opportunity for structure-tailored signal processing, such as multivariate analysis.
