Scientists designing golden nanopill for drug delivery
US-based researchers are developing a microscopic gold pill that can navigate the bloodstream and be triggered to release drugs using laser light. The team demonstrated gold nanoparticle-coated liposomes, which are spherical sacs enclosing a watery core that can be used to carry drugs into desired tissues. After delivery, the nanoparticles can be excreted by the body via renal system.
