Nanoparticles that can slip through mucus barriers shown to protect against herpes infections
Johns Hopkins researchers say they have demonstrated, for the first time in animals, that nanoparticles can slip through mucus to deliver drugs directly to tissue surfaces in need of protection. The researchers used these mucus-penetrating particles (MPPs) to protect against vaginal herpes infections in mice and the goal is to create similar MPPs to deliver drugs that protect humans against sexually transmitted diseases or even treat cancer.
