The field of genetic modification relies on a variety of delivery vehicles to introduce modified genetic material into target cells. These vehicles play a essential role in enabling precise gene editing and manipulation. Some common classes of delivery vehicles include viral particles, liposomes, and engineered nanoparticles. Each type presents unique advantages and restrictions. The choice of method depends on factors such as the target cell type, the size and nature of the genetic payload, and the desired duration of gene expression.
Liposomes 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. Engineered nanoparticles offer greater controllability and reduced immunogenicity, but their delivery efficiency can be constrained.
