The field of genetic modification relies on a variety of carriers to introduce transformed genetic material into target cells. These systems play a essential role in enabling targeted gene editing and manipulation. Some common categories of delivery vectors include viral vectors, liposomes, and artificial nanoparticles. Each type presents unique properties and drawbacks. The choice of system depends on factors such as the species, the size and nature of the genetic material, and the desired duration of gene expression.
Viral vectors can successfully deliver genes into a wide range of cells, but they may induce immune responses or integrate into the host genome, potentially causing unintended consequences. Engineered nanoparticles offer greater targeting and reduced immunogenicity, but their delivery efficiency can be constrained.
