Abstract Aptamers are single stranded DNA or RNA ligands which can be selected for different targets starting from a huge library of molecules containing randomly created sequences. Aptamers have been selected to bind very different targets, from proteins to small organic dyes. In addition to the very important aspect of having an unlimited source of identical affinity recognition molecules available due to the selection process, aptamers can offer advantages over antibodies that make them very promising for analytical applications. The use of aptamers as therapeutic tools is nowadays well established. On the contrary, the analytical application of aptamers in diagnostic devices or in systems for environmental and food analysis, is still under investigation and the scientific community still need further research to demonstrate the advancements brought by this new kind of ligands. This review will focus on these latter applications with particular attention to the detection of food pathogens, terrorism threat agents, thrombin and cytokines.
