The field of genetic modification relies on a variety of carriers to introduce transformed genetic material into target cells. These systems play a crucial role in enabling precise gene editing and manipulation. Some common categories of delivery systems include viral vectors, liposomes, and synthetic nanoparticles. Each type possesses unique advantages and vectors in genetic engineering drawbacks. The choice of delivery vehicle depends on factors such as the target cell type, the size and nature of the genetic material, and the desired duration of gene expression.
Liposomes can successfully deliver genes into a wide range of cells, but they may initiate immune responses or integrate into the host genome, potentially causing unintended consequences. Synthetic nanoparticles offer greater precision and reduced immunogenicity, but their transport efficiency can be limited.
