The field of genetic modification relies on a variety of delivery vehicles to introduce transformed genetic material into target cells. These systems play a crucial role in enabling targeted gene editing and manipulation. Some common categories of delivery vehicles include viral vectors, liposomes, and engineered nanoparticles. Each type offers unique characteristics and restrictions. The choice of delivery vehicle 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 initiate immune responses or insert into the host genome, potentially causing unintended consequences. Artificial nanoparticles offer greater targeting and reduced immunogenicity, but their transfection efficiency can be limited.
