The field of genetic modification relies on a variety of delivery vehicles 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 vectors include viral particles, liposomes, and synthetic nanoparticles. Each type possesses unique characteristics and limitations. The choice of system depends on factors such as the organism, the size and nature of the genetic construct, and the desired duration of gene expression.
Nanoparticles can efficiently deliver genes into a wide range of cells, but they may initiate immune responses or incorporate into the host genome, potentially causing unintended consequences. Synthetic nanoparticles offer greater controllability and reduced immunogenicity, but their transport efficiency can be limited.
