Abstract
Nucleic acid (NA)-functionalized nanomaterials (NMs) have received considerable attention in recent years. The use of nucleic acid (DNA/RNA) for surface functionalization of NMs offers the ability to directly address desired targets and coat NMs with biocompatible polymers, such as poly [(ethylene)] glycol (PEG) and polyacrylamide (PA), enhancing the utility of these complexes in biomedicine. In particular, the target-specific recognition capacity of surface-functionalized NMs has opened up new avenues for disease diagnosis and therapy. This review focuses on the biological applications of a special type of nucleic acid, termed aptamer, conjugated with a variety of NMs for a wide spectrum of applications in nanobiomedicine.
