The field of genetic modification utilizes a variety of vectors to introduce modified genetic material into target cells. These tools play a vital role in enabling specific gene editing and manipulation. Some common types of delivery vehicles include viral vectors, liposomes, and artificial nanoparticles. Each type presents 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.
Viral vectors can efficiently deliver genes into a wide range of cells, but they may initiate immune responses or integrate into the host genome, potentially causing unintended consequences. Artificial nanoparticles offer greater precision and reduced immunogenicity, but their delivery efficiency can be restricted.
