The field of genetic modification employs a variety of delivery vehicles to introduce altered genetic material into target cells. These systems play a crucial role in enabling precise gene editing and manipulation. Some common types of delivery vehicles include viral carriers, liposomes, and engineered nanoparticles. Each type offers unique characteristics and drawbacks. The choice of system depends on factors such as the organism, the size and nature of the genetic material, and the desired duration of gene expression.
Nanoparticles 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 transfection efficiency can be constrained.
