The field of genetic modification employs a variety of vectors to introduce transformed genetic material into target cells. These systems play a crucial role in enabling targeted gene editing and manipulation. Some common categories of delivery vectors include viral particles, liposomes, and artificial nanoparticles. Each type possesses unique properties and restrictions. The choice of system depends on factors such as the organism, the size and nature of the genetic payload, and the desired duration of gene expression.
Nanoparticles can effectively deliver genes into a wide range of cells, but they may initiate immune responses or integrate into the host genome, potentially causing unintended consequences. Engineered nanoparticles offer greater targeting and reduced immunogenicity, but their transport efficiency can be limited.
