The field of genetic modification employs a variety of carriers to introduce altered genetic material into target cells. These tools play a vital role in enabling specific gene editing and manipulation. Some common types of delivery systems include viral carriers, liposomes, and artificial nanoparticles. Each type offers unique properties and restrictions. The choice of method depends on factors such as the organism, the size and nature of the genetic material, and the desired duration of gene expression.
Liposomes can effectively deliver genes into a wide range of cells, but they may initiate immune responses or integrate into the host genome, potentially causing unintended consequences. Artificial nanoparticles offer greater targeting and reduced immunogenicity, but their transfection efficiency can be constrained.
