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