Man Made Particles May Become "Antibiotics of the Future"
Researchers at the Massachusetts Institute of Technology (MIT) have developed particles that can fights infectionsso effectively that they've been referred to as the "antibiotics of the future."
The scientists modeled these man made particles on bacteriophages – viruses that infect and kill bacteria. Unlike commonly used antibiotics, bacteriophages target specific bacteria and leave friendly bacteria intact. The problem is that they also can cause side effects when they kill bacteria by causing the cell to burst and release dangerous toxins.
But the new particles were engineered so that they were able to kill the bacteria without bursting the cells, resulting in a treatment that was highly targeted without causing the side effects.
This development could represent a major step in addressing the pressing problem of "superbugs" developing resistance to treatment of infections with traditional antibiotics.
