| Popis: | Aptamers are nucleic acid molecules that mimic antibodies by folding into complex 3D shapes that bind to specific targets. Although some aptamers exist naturally as the ligand-binding elements of riboswitches, most are generated in vitro and can be tailored for a specific target. Relative to antibodies, aptamers benefit from their ease of generation, low production cost, low batch-to-batch variability, reversible folding properties and low immunogenicity. However, the true value of aptamers lies in the simplicity by which these molecules can be engineered into sensors, actuators and other devices that are often central to emerging technologies. This Review examines changing trends in aptamer technology by analysing the first quarter century of aptamer data that is available in the scientific literature (1990–2015). We highlight specific examples that showcase the use of aptamers in key applications, discuss challenges that have impeded the success of aptamers in practical applications, provide suggestions for choosing chemical modifications that can lead to enhanced activity or stability, and propose standards for the characterization of aptamers in the scientific literature. Aptamers are nucleic acid molecules that can be evolved to bind to specific molecular targets and have found applications in technologies such as sensors and actuators. This Review provides a critical analysis of the first 25 years of aptamer research. |
