The field of genetic modification employs a variety of delivery vehicles to introduce transformed genetic material into target cells. These tools play a essential role in enabling precise gene editing and manipulation. Some common categories of delivery systems include viral particles, liposomes, and synthetic nanoparticles. Each type possesses unique advantages and restrictions. The choice of system depends on factors such as the target cell type, 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 insert into the host genome, potentially causing unintended consequences. Artificial nanoparticles offer greater targeting and reduced immunogenicity, but their delivery efficiency can be restricted.
