'Decoy' nanoparticles can block HIV and prevent infection

Flipping the standard viral drug targeting approach on its head, engineers at the University of California San Diego have developed a promising new "nanosponge" method for preventing HIV from proliferating in the body: coating polymer nanoparticles with the membranes of T helper cells and turning them into decoys to intercept viral particles and block them from binding and infiltrating the body's actual immune cells.
