Luminescence-based sensing applications range from agriculture to biology, including
medicine and environmental care, which indicates the importance of this technique as a detection tool.
Luminescent optical sensors are required to be highly stable, sensitive, and selective, three crucial
features that can be achieved by fabricating them by means of the layer-by-layer nano-assembly
technique. This method permits us to tailor the sensors0 properties at the nanometer scale, avoiding
luminophore aggregation and, hence, self-quenching, promoting the diffusion of the target analytes,
and building a barrier against the undesired molecules. These characteristics give rise to the
fabrication of custom-made sensors for each particular application. [--]
