The field of genetic modification employs a variety of delivery vehicles to introduce transformed genetic material into target cells. These vehicles play a crucial role in enabling specific gene editing and manipulation. Some common classes of delivery vehicles include viral carriers, liposomes, and synthetic nanoparticles. Each type offers unique advantages and limitations. The choice of system depends on factors such as the species, the size and nature of the genetic payload, and the desired duration of gene expression.
Liposomes can effectively deliver genes into a wide range of cells, but they may trigger immune responses or insert into the host genome, potentially causing unintended consequences. Synthetic nanoparticles offer greater targeting and reduced immunogenicity, but their transport efficiency can be restricted.
