The field of genetic modification utilizes a variety of delivery vehicles to introduce modified genetic material into target cells. These vehicles play a essential role in enabling specific gene editing and manipulation. Some common categories of delivery systems include viral particles, liposomes, and artificial nanoparticles. Each type presents unique advantages and limitations. 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.
Liposomes 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 targeting and reduced immunogenicity, but their transfection efficiency can be constrained.
