The field of genetic modification relies on a variety of delivery vehicles to introduce transformed genetic material into target cells. These tools play a essential role in enabling specific gene editing and manipulation. Some common categories of delivery vehicles include viral carriers, liposomes, and synthetic nanoparticles. Each type possesses unique properties and drawbacks. 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 efficiently deliver genes into a wide range of cells, but they may trigger immune responses or incorporate into the host genome, vectors in genetic engineering potentially causing unintended consequences. Synthetic nanoparticles offer greater precision and reduced immunogenicity, but their delivery efficiency can be limited.
