The field of genetic modification utilizes a variety of delivery vehicles to introduce transformed genetic material into target cells. These tools play a essential role in enabling precise gene editing and manipulation. Some common categories of delivery vectors include viral carriers, 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.
Nanoparticles 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. Engineered nanoparticles offer greater precision and reduced immunogenicity, but their delivery efficiency can be limited.
