The field of genetic modification relies on a variety of delivery vehicles to introduce modified genetic material into target cells. These vehicles play a essential role in enabling precise gene editing and manipulation. Some common types of delivery vehicles include viral vectors, liposomes, and synthetic nanoparticles. Each type presents unique advantages and limitations. The choice of system depends on factors such as the species, the size and nature of the genetic payload, and the desired duration of gene expression.
Viral vectors can efficiently deliver genes into a wide range of cells, but they may induce immune responses or insert into the host genome, potentially causing unintended consequences. Artificial nanoparticles offer greater precision and reduced immunogenicity, but their delivery efficiency can be constrained.
