The field of genetic modification utilizes a variety of carriers to introduce modified genetic material into target cells. These systems play a vital role in enabling targeted gene editing and manipulation. Some common classes of delivery vectors include viral carriers, liposomes, and synthetic nanoparticles. Each type offers unique advantages and drawbacks. 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.
Viral vectors can successfully deliver genes into a wide range of cells, but they may initiate immune responses or insert into the host genome, potentially causing unintended consequences. Artificial nanoparticles offer greater controllability and reduced immunogenicity, but their transport efficiency can be constrained.
