Aptamers are in vitro selected oligonucleotides capable of specific, high-affinity binding to a wide variety of target molecules. These features enable their application in diagnostics, therapeutics, targeted delivery, fluorescence imaging, and biosensing. Aptamers are isolated via the systematic evolution of ligands by exponential enrichment (SELEX), an iterative cycle of selection and amplification steps that enriches a randomly synthesised oligonucleotide...
