The field of genetic modification utilizes a variety of delivery vehicles to introduce transformed genetic material into target cells. These tools play a essential role in enabling specific gene editing and manipulation. Some common categories of delivery vectors include viral vectors, liposomes, and artificial nanoparticles. Each type possesses unique characteristics and limitations. The choice of system depends on factors such as the species, the size and nature of the genetic construct, and the desired duration of gene expression.
Viral vectors can efficiently 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 controllability and reduced immunogenicity, but their delivery efficiency can be restricted.
