The field of genetic modification relies on a variety of delivery vehicles to introduce altered genetic material into target cells. These systems play a essential role in enabling targeted gene editing and manipulation. Some common types of delivery systems include viral carriers, liposomes, and engineered nanoparticles. Each type offers unique properties and limitations. 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.
Nanoparticles 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 transport efficiency can be constrained.
