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 specific gene editing and manipulation. Some common categories of delivery vehicles include viral vectors, liposomes, and artificial nanoparticles. Each type presents unique properties and restrictions. 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 effectively 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 transport efficiency can be restricted.
