The field of genetic modification utilizes a variety of delivery vehicles to introduce transformed genetic material into target cells. These tools play a crucial role in enabling specific gene editing and manipulation. Some common classes of delivery systems include viral particles, liposomes, and artificial nanoparticles. Each type offers unique characteristics and drawbacks. The choice of delivery vehicle depends on factors such as the species, the size and nature of the genetic payload, and the desired duration of gene expression.
Liposomes can effectively 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 controllability and reduced immunogenicity, but their delivery efficiency can be limited.
