Robots in Your Bloodstream

I know too many people who have cancer; I’ve observed their struggles. In the middle of the night I have thought of them and their battles and I have prayed for them. I’ve watched some of them “beat” the illness; I’ve watched others die. So when I see a development such as this which has some promise of effective cancer treatment, it always excites me.

The next big step in cancer treatment might be small enough to balance on a grain of salt.

Researchers at the Israel Institute of Technology in Haifa have developed a miniature crawling robot, called ViRob, that can crawl through your lungs, find a tumor, and zap it with drugs. The bot, which is one millimeter long and four millimeters from end to end, can snake its way through the body, slipping into blood vessels and navigating through the respiratory and digestive systems, Innerspace style.

Other mini-robots have been designed to take a voyage into the body. But thanks to tiny arms that help it grip vessel walls , ViRob is the first microbot that can tunnel between different body cavities. It’s controlled by an electromagnetic field outside of the robot that creates a vibration that propels ViRob forward.

In lab tests, the robot has traveled up to nine millimeters per second and can commute through body fluids ranging from blood to bile, making it a versatile tool that can race through a vein and burrow into an organ. Its designers even hope to accessorize it with equipment such as a wee camera and a mini pair of tongs, to get that close-up view of those alveoli at work.  The researchers are officially introducing the device at the upcoming ILSI-Biomed Conference in Tel Aviv.

One question I might have, and maybe you know the answer to it: What are the chances of the little tiny arms actually puncturing tissue walls causing other internal problems like bleeding?


WOW! This is quite interesting! It would be great if these little robots could do such a work.

Hi, Linda. Seems far-fetched but if people who died 100 years ago came back to this earth, they would not be able to believe the advances that have been made in technology. I am hoping a cure (or at least an effective treatment) for cancer can be found. It is such a vicious disease.

Love you.


I am amused that the possibly related posts include references to Fantastic Voyage. These little robots sound remarkably nanites on Star Trek: Next Generation. I have a friend who is battling cancer right now. If these can help, I’m all for it, too.

Hi, Becky. I’m with you–have friends who are battling this dreadful situation. Do hope something can be done for them.
