The field of genetic modification employs a variety of delivery vehicles to introduce modified genetic material into target cells. These tools play a vital role in enabling precise gene editing and manipulation. Some common categories of delivery systems include viral carriers, liposomes, and synthetic 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 payload, and the desired duration of gene expression.
Liposomes can efficiently 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 limited.
