“…Due to the high selectivity and high affinity of the aptamer for the target molecule, it is also termed a “chemical antibody”. A variety of research studies have demonstrated that aptamers are capable of interacting with a variety of targets, including metal ions, amino acids, antibiotics, coenzymes, polypeptides, and fluorophore molecules [1] , [2] , [3] , [4] . Recognition and interaction with different target molecules allow aptamers be applied as biosensors, target recognition and target delivery.…”
