The field of genetic modification relies on a variety of carriers to introduce altered genetic material into target cells. These systems play a crucial role in enabling precise gene editing and manipulation. Some common categories of delivery vectors include viral vectors, liposomes, and synthetic nanoparticles. Each type possesses unique advantages and drawbacks. The choice of system depends on factors such as the organism, the size and nature of the genetic payload, and the desired duration of gene expression.
Liposomes can efficiently deliver genes into a wide range of cells, but they may initiate immune responses or integrate into the host genome, potentially causing unintended consequences. Synthetic nanoparticles offer greater precision and reduced immunogenicity, but their delivery efficiency can be limited.
