Construction of Polymeric DNA Network and Application for Cell Manipulation

Abstract

Comprehensive Summary Deoxyribonucleic acid (DNA) is a biomacromolecule, as well as a polymeric material, whose sequences with different manipulative structures enable them to implement a series of functions, such as reorganization, target, and catalysis. Compared to existing traditional materials incapable of multifunctional integration, the polymeric DNA network is a form of material that can achieve functional integration while maintaining specific DNA properties. Furthermore, precise target enabled by DNA network is one of the most essential components of cellular manipulation. Hence, the DNA network is indispensable and irreplaceable to cell manipulation that it is a versatile tool for the understanding of basic laws of living life and treatments of diseases, such as cell isolation, cell delivery, and cell interference. Herein, the construction of polymeric DNA network is briefly introduced from the aspects of assembly modules, construction methods, and properties. Subsequently, the applications of DNA network in the field of cell manipulation, including cell isolation and encapsulation, intracellular inference and detection, and tumor therapy are summarized. Finally, we provide some prospects for further research and applications of DNA network for cell manipulation.

Exploration of integrated teaching model for undergraduate and graduate students -- taking the course of questionnaire survey design and data analysis methods as an example

“…The existing curriculum design neglects the connection between undergraduate and graduate education. Currently, undergraduate and graduate education are seen as isolated stages 4 . During undergraduate studies, emphasis is placed on textbooks and theory, while during graduate studies, emphasis is placed on specialization and practice.…”

Advances in Rolling Circle Amplification (RCA)‐Based DNA‐Functional Materials for Cancer Diagnosis and Therapy

“…Hydrogel is a kind of extremely hydrophilic 3D network gels with properties similar to the extracellular matrix, thus providing unique advantages in biological vesicle capture and delivery. [ 56 ] RCA‐based DNA hydrogel was first achieved by the research group of Prof. Dan Luo in 2012. [ 57 ] Single type of ultralong ssDNA generated by RCA can form hydrogel by physical entanglement, which typically requires an RCA reaction time of more than 24 h. [ 58 ] Due to the long reaction time and low synthesis efficiency of this method, ultralong ssDNA can hybrid with other positively charged functional materials to form hybrid hydrogel (Figure 2A).…”
