The field of genetic modification relies on a variety of carriers to introduce modified genetic material into target cells. These vehicles play a vital role in enabling targeted gene editing and manipulation. Some common classes of delivery vehicles include viral particles, liposomes, and artificial nanoparticles. Each type offers unique properties and limitations. The choice of method depends on factors such as the species, the size and nature of the genetic construct, and the desired duration of gene expression.
Liposomes can successfully deliver genes into a wide range of cells, but they may initiate immune responses or integrate into the host genome, potentially causing unintended consequences. Artificial nanoparticles offer greater targeting and reduced immunogenicity, but their delivery efficiency can be constrained.
