The occurrence, development, and metastasis of tumors often entail abnormal expression of genetic substances. Monitoring and regulating changes in intracellular nucleic acid substances hold promise for achieving accurate tumor diagnosis and effective treatment. However, the effectiveness of integrated tumor diagnosis and treatment based on functional nucleic acids still needs to be improved. In this study, we engineered a multifunctional nucleic acid delivery system grounded in a cationic covalent organic framework carrier. This system not only showcases effective gene silencing but also boasts high sensitivity in detecting miR21 levels within tumor cells, enabling real-time monitoring of tumor gene therapy efficacy. The construction of this integrated functional nucleic acid delivery platform provides new ideas for precise tumor detection and effective tumor treatment.
