The field of genetic modification employs a variety of delivery vehicles to introduce altered genetic material into target cells. These systems play a crucial role in enabling precise gene editing and manipulation. Some common classes of delivery vectors include viral vectors, liposomes, and engineered nanoparticles. Each type possesses unique advantages and limitations. The choice of system depends on factors such as the target cell type, the size and nature of the genetic material, and the desired duration of gene expression.
Liposomes can effectively deliver genes into a wide range of cells, but they may trigger immune responses or insert into the host genome, potentially causing unintended consequences. Engineered nanoparticles offer greater targeting and reduced immunogenicity, but their transport efficiency can be restricted.
