The field of genetic modification utilizes a variety of delivery vehicles to introduce modified genetic material into target cells. These systems play a vital role in enabling targeted gene editing and manipulation. Some common classes of delivery vectors include viral vectors, liposomes, and engineered nanoparticles. Each type possesses unique characteristics and limitations. The choice of method depends on factors such as the organism, the size and nature of the genetic material, and the desired duration of gene expression.
Viral vectors can effectively deliver genes into a wide range of cells, but they may trigger immune responses or insert into the host genome, potentially causing unintended consequences. Synthetic nanoparticles offer greater controllability and reduced immunogenicity, but their delivery efficiency can be limited.
