The field of genetic modification employs a variety of delivery vehicles to introduce altered genetic material into target cells. These vehicles play a crucial role in enabling precise gene editing and manipulation. Some common classes of delivery vectors include viral particles, liposomes, and artificial nanoparticles. Each type offers unique advantages and limitations. The choice of delivery vehicle depends on factors such as the species, 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 initiate immune responses or incorporate into the host genome, potentially causing unintended consequences. Artificial nanoparticles offer greater targeting and reduced immunogenicity, but their transfection efficiency can be restricted.
