DNA Hydrogels for Cancer Diagnosis and Therapy.

Abstract

Nucleic acids, because of their precise pairing and simple composition, have emerged as excellent materials for the formation of gels. The application of DNA hydrogels in the diagnosis and therapy of cancer has expanded significantly through research on the properties and functions of nucleic acids. Functional nucleic acids (FNAs) such as aptamers, Small interfering RNA (siRNA), and DNAzymes have been incorporated into DNA hydrogels to enhance their diagnostic and therapeutic capabilities. This review discusses various methods for forming DNA hydrogels, with a focus on pure DNA hydrogels. We then explore the innovative applications of DNA hydrogels in cancer diagnosis and therapy. DNA hydrogels have become essential biomedical materials, and this review provides an overview of current research findings and the status of DNA hydrogels in the diagnosis and therapy of cancer, while also exploring future research directions.
