Area of Science:

  • Polymer Chemistry
  • Biomaterials Science
  • Gene Therapy

Background:

  • Dynamic covalent polymers (DCPs) utilize reversible covalent bonds and non-covalent interactions within adaptive constitutional dynamic chemistry.
  • DCPs are emerging as promising candidates for gene delivery due to their inherent responsiveness and adaptability.
  • This adaptability allows for the design of vectors that can self-adjust to nucleic acid cargo and respond to biological environments.

Purpose of the Study:

  • To review the structural characteristics of molecular building blocks used in DCPs for gene delivery.
  • To explore the diverse architectures (linear, 2D, 3D) of DCPs developed for this application.
  • To examine the mechanisms of covalent and supramolecular self-assembly in nucleic acid recognition and delivery by DCPs.

Main Methods:

  • Literature review focusing on DCPs in gene delivery.
  • Analysis of molecular building block structures and polymer architectures.
  • Investigation of self-assembly processes, including templating by nucleic acids and response to biomolecular targets.

Main Results:

  • DCPs can be engineered with specific structural features and architectures for gene delivery.
  • Covalent and supramolecular interactions facilitate nucleic acid binding and release.
  • Emerging examples demonstrate adaptive self-assembly templated by nucleic acids, with responsiveness to cell membrane targets.

Conclusions:

  • DCPs present a versatile platform for developing sophisticated gene delivery systems.
  • The adaptive nature of DCPs allows for optimization of vector-cargo interactions and environmental responsiveness.
  • Future research can leverage DCPs for enhanced cellular uptake and targeted gene therapy applications.
