Introduction to the Aptamers Aptamers are single-stranded oligonucleotide molecules that are able to bind to a specific target molecule with high affinity and specificity. They are used to detect and manipulate biological molecules, such as proteins, enzymes, small molecules or even whole cells. Aptamers are generated using a process known as Systematic Evolution of Ligands by Exponential Enrichment (SELEX), which involves in vitro selection of a large pool of random oligonucleotide sequences...
