The field of genetic modification relies on a variety of vectors to introduce transformed genetic material into target cells. These systems play a essential role in enabling precise gene editing and manipulation. Some common categories of delivery systems include viral carriers, liposomes, and synthetic nanoparticles. Each type presents unique characteristics and limitations. The choice of delivery vehicle depends on factors such as the target cell type, the size and nature of the genetic payload, and the desired duration of gene expression.
Liposomes can successfully 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 delivery efficiency can be restricted.
