The field of genetic modification relies on a variety of delivery vehicles to introduce altered genetic material into target cells. These vehicles play a essential role in enabling precise gene editing and manipulation. Some common classes of delivery vehicles include viral particles, liposomes, and synthetic nanoparticles. Each type offers unique advantages and restrictions. The choice of method depends on factors such as the target cell type, the size and nature of the genetic payload, 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 incorporate into the host genome, potentially causing unintended consequences. Artificial nanoparticles offer greater precision and reduced immunogenicity, but their delivery efficiency can be limited.
