Bifunctional RNA-Targeting Deoxyribozyme Nanodevice as a Potential Theranostic Agent

Area of Science:

• Biotechnology
• Molecular Biology
• Nanotechnology

Background:

• Theranostics combine disease diagnosis and therapy.
• Developing precise tools for simultaneous detection and treatment is crucial.

Purpose of the Study:

• To design a DNA nanodevice capable of simultaneous RNA target detection and cleavage.
• To achieve high selectivity in RNA recognition under physiological conditions.

Main Methods:

• Design and synthesis of a novel DNA nanodevice.
• Testing the nanodevice's ability to detect and cleave a specific RNA target.
• Evaluating the selectivity and performance under near physiological conditions.

Main Results:

• The DNA nanodevice successfully reported the presence of the RNA target via increased fluorescence.
• The nanodevice effectively cleaved the targeted RNA.
• High selectivity for RNA target recognition was demonstrated under near physiological conditions.

Conclusions:

• The developed DNA nanodevice functions as a theranostic tool.
• This approach provides a foundation for creating DNA nanomachines for diagnostics and therapy.
• Potential applications include treating viral infections, cancer, and genetic disorders.
