Tools for Genetic Engineering
The field of genetic modification employs a variety of delivery vehicles to introduce altered genetic material into target cells. These tools play a vital role in enabling specific gene editing and manipulation. Some common classes of delivery systems include viral vectors, liposomes, and synthetic nanoparticles. Each type offers unique properties and drawbacks. The choice of delivery vehicle depends on factors such as the species, the size and nature of the genetic construct, and the desired duration of gene expression.
Viral vectors can efficiently deliver genes into a wide range of cells, but they may induce immune responses or integrate into the host genome, potentially causing unintended consequences. Engineered nanoparticles offer greater controllability and reduced immunogenicity, but their transfection efficiency can be restricted.
