The field of genetic modification employs a variety of delivery vehicles to introduce transformed genetic material into target cells. These systems play a essential role in enabling specific gene editing and manipulation. Some common categories of delivery vehicles include viral carriers, liposomes, and artificial nanoparticles. Each type possesses unique properties and limitations. 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 effectively 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 controllability and reduced immunogenicity, but their transport efficiency can be restricted.
