The field of genetic modification utilizes a variety of vectors to introduce transformed genetic material into target cells. These systems play a crucial role in enabling specific gene editing and manipulation. Some common categories here of delivery vectors include viral particles, liposomes, and synthetic nanoparticles. Each type presents unique advantages and limitations. The choice of method 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 effectively deliver genes into a wide range of cells, but they may trigger immune responses or integrate into the host genome, potentially causing unintended consequences. Artificial nanoparticles offer greater controllability and reduced immunogenicity, but their delivery efficiency can be restricted.
