The field of genetic modification relies on a variety of delivery vehicles to introduce transformed genetic material into target cells. These vehicles play a vital role in enabling targeted gene editing and manipulation. Some common classes of delivery vectors include viral carriers, liposomes, and synthetic nanoparticles. Each type offers unique advantages and drawbacks. The choice of delivery vehicle depends on factors such as the organism, the size and nature of the genetic construct, and the desired duration of gene expression.
Nanoparticles can effectively deliver genes into a wide range of cells, but they may trigger 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 limited.
