The field of genetic modification relies on a variety of delivery vehicles to introduce altered genetic material into target cells. These tools play a crucial role in enabling specific gene editing and manipulation. Some common categories of delivery vectors include viral particles, liposomes, and artificial nanoparticles. Each type presents unique properties and drawbacks. The choice of delivery vehicle depends on factors such as the target cell type, the size and nature of the genetic construct, and the desired duration of gene expression.
Nanoparticles can efficiently deliver genes into a wide range of cells, but they may induce immune responses or insert into the host genome, potentially causing unintended consequences. Artificial nanoparticles offer greater precision and reduced immunogenicity, but their delivery efficiency can be constrained.
