The field of genetic modification employs a variety of vectors to introduce altered genetic material into target cells. These systems play a vital role in enabling targeted gene editing and manipulation. Some common classes of delivery vehicles include viral vectors, liposomes, and artificial nanoparticles. Each type possesses unique advantages and limitations. The choice of method depends on factors such as the target cell type, the size and nature of the genetic construct, and the desired duration of gene expression.
Liposomes can efficiently deliver genes into a wide range of cells, but they may induce immune responses or incorporate into the host genome, potentially causing unintended consequences. Artificial nanoparticles offer greater precision and reduced immunogenicity, but their delivery efficiency can be constrained.
