What is it about?
This review article discusses the development of optical sensors, devices that can detect and measure things using light, which have specific requirements: they need to be reliable, fast, easy to use, and very affordable. Additionally, it's becoming increasingly important for these sensors to work without needing a constant energy source and for their components to be recyclable. The article explores how existing plasmonic concepts (involving the interaction of light with metallic nanostructures) and advancements in nanofabrication can meet these demanding requirements. It focuses on how combining different properties of light and materials can lead to sensors that are highly sensitive while keeping energy losses low. The article also looks at the latest techniques in nanostructure production and self-assembly to create sensors that measure changes in the refractive index of materials. In summary, it's about creating state-of-the-art, cost-effective optical sensors by blending the best of both light and nanotechnology.
