The field of genetic modification utilizes a variety of vectors to introduce modified genetic material into target cells. These vehicles play a crucial role in enabling precise gene editing and manipulation. Some common types of delivery vehicles include viral particles, liposomes, and synthetic nanoparticles. Each type possesses unique advantages and drawbacks. The choice of delivery vehicle 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 effectively deliver genes into a wide range of cells, but they may initiate immune responses or insert into the host genome, potentially causing unintended consequences. Synthetic nanoparticles offer greater precision and reduced immunogenicity, but their delivery efficiency can be restricted.
