The field of genetic modification utilizes a variety of delivery vehicles to introduce transformed genetic material into target cells. These vehicles play a crucial role in enabling targeted gene editing and manipulation. Some common categories of delivery vehicles include viral vectors, liposomes, and artificial nanoparticles. Each type presents unique characteristics and restrictions. The choice of method depends on factors such as the species, the size and nature of the genetic material, and the desired duration of gene expression.
Nanoparticles can successfully deliver genes into a wide range of cells, but they may initiate immune responses or incorporate into the host genome, potentially causing unintended consequences. Artificial nanoparticles offer greater controllability and reduced immunogenicity, but their transfection efficiency can be constrained.
