How tiny ‘natural nanobots’ attack cancerous cells

Image: Polytechnique Montréal Chemotherapy kills cancer, but it also attacks healthy cells. This unfortunate phenomenon makes us sick and can cause permanent damage to our bodies. Of course the good (saving lives) still outweighs the bad, so we continue to use powerful drugs to kill cancer. But with the latest technology, we can do better. Delivering medicine directly where it’s needed not only minimizes side effects but also makes the drugs more effective. That’s why researchers are designing tiny robots to precisely carry drugs to cancerous cells while leaving nearby healthy cells alone. Imagine armies of millions of miniature robots traveling through blood streams to sneak up on cancerous cells. It sounds like a fantasy because it is. Despite admirable efforts by scientists, many technological challenges still need to be…
