The field of genetic modification employs a variety of vectors to introduce transformed genetic material into target cells. These tools play a crucial role in enabling specific gene editing and manipulation. Some common classes of delivery vectors include viral vectors, liposomes, and engineered nanoparticles. Each type offers unique properties and drawbacks. 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 induce immune responses or insert into the host genome, potentially causing unintended consequences. Synthetic nanoparticles offer greater targeting and reduced immunogenicity, but their transfection efficiency can be limited.
