The field of genetic modification employs a variety of vectors to introduce modified 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 carriers, liposomes, and engineered nanoparticles. Each type possesses unique properties and drawbacks. 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 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. Artificial nanoparticles offer greater precision and reduced immunogenicity, but their transport efficiency can be constrained.
