The field of genetic modification relies on a variety of delivery vehicles to introduce modified genetic material into target cells. These tools play a crucial role in enabling targeted gene editing and manipulation. Some common categories of delivery vehicles include viral carriers, liposomes, and engineered nanoparticles. Each type offers unique characteristics and drawbacks. The choice of system 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 insert into the host genome, potentially causing unintended consequences. Engineered nanoparticles offer greater controllability and reduced immunogenicity, but their transport efficiency can be restricted.
