Nano-Sized Bomb Targets Tumors
Traditional attempts to destroy cancerous tumors involve treatments such as chemotherapy that kill healthy cells right along with mutated ones, often leaving patients weak, nauseous, hairless and vulnerable to infection.
But now biologists and engineers at the Massachusetts Institute of Technology have engineered a dual-chamber molecular bomb designed to infiltrate a tumor, shut down its blood vessels — thereby sealing off the exits — and detonate a dose of cancer-killing toxins.
