The field of genetic modification employs a variety of carriers to introduce altered genetic material into target cells. These tools play a vital role in enabling specific gene editing and manipulation. Some common types of delivery systems include viral particles, liposomes, and engineered nanoparticles. Each type offers unique properties and limitations. The choice of delivery vehicle 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 induce immune responses or insert into the host genome, potentially causing unintended consequences. Artificial nanoparticles offer greater targeting and reduced immunogenicity, but their transport efficiency can be limited.
