Abstract
Nucleic acid aptamers, selected from a synthesized library of random single-stranded oligonucleotides by systematic evolution of ligands by exponential enrichment (SELEX), are oligonucleotide ligands binding to target molecules with high specificity and affinity. Nucleic acid aptamers have similar functions to antibodies, but possess the advantages of wider range of targets, better stability, easier modification and synthesis, showing promising prospects for diagnosis and treatment of diseases. In terms of digestive diseases, nucleic acid aptamers have been applied in the research of tumor markers, anti-tumor therapy, hepatitis virus C and liver imaging.
