The field of genetic modification relies on a variety of carriers to introduce transformed genetic material into target cells. These systems play a vital role in enabling precise gene editing and manipulation. Some common classes of delivery systems include viral carriers, liposomes, and synthetic nanoparticles. Each type possesses unique characteristics and restrictions. The choice of delivery vehicle depends on factors such as the target cell type, the size and nature of the genetic material, and the desired duration of gene expression.
Viral vectors can efficiently deliver genes into a wide range of cells, but they may trigger immune responses or incorporate into the host genome, potentially causing unintended consequences. Artificial nanoparticles offer greater controllability and here reduced immunogenicity, but their transfection efficiency can be limited.
