Harnessing Nanomaterials for Enhanced DNA-Based Biosensing and Therapeutic Performance.

Abstract

The integration of nanomaterials with DNA-based systems has emerged as a transformative approach in biosensing and therapeutic applications. Unique features of DNA, like its programmability and specificity, complement the diverse functions of nanomaterials, leading to the creation of advanced systems for detecting biomarkers and delivering treatments. Here, we review the developments in DNA-nanomaterial conjugates, emphasizing their enhanced functionalities and potential across various biomedical applications. We first discuss the methodologies for synthesizing these conjugates, distinguishing between covalent and non-covalent interactions. We then categorize DNA-nanomaterials conjugates based on the properties of the DNA and nanomaterials involved, respectively. DNA probes are classified by their application into biosensing or therapeutic uses, and, several nanomaterials are highlighted by their recent progress in living biological. Finally, we discuss the current challenges and future prospects in this field, anticipating that significant progress in DNA-nanomaterial conjugates will greatly enhance precision medicine.
