The field of genetic modification relies on a variety of delivery vehicles to introduce transformed genetic material into target cells. These tools play a crucial role in enabling targeted gene editing and manipulation. Some common categories of delivery vehicles include viral particles, liposomes, and synthetic nanoparticles. Each type presents unique advantages and limitations. The choice of system depends on factors such as the organism, the size and nature of the genetic construct, and the desired duration of gene expression.
Liposomes 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. Engineered nanoparticles offer greater precision and reduced immunogenicity, but their transfection efficiency can be restricted.
