The field of genetic modification employs a variety of carriers to introduce altered genetic material into target cells. These vehicles play a crucial role in enabling targeted gene editing and manipulation. Some common types of delivery vectors include viral particles, liposomes, and synthetic nanoparticles. Each type possesses unique characteristics and restrictions. The choice of method depends on factors such as the target cell type, the size and nature of the genetic construct, and the desired duration of gene expression.
Viral vectors 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 transfection efficiency can be restricted.
