Could nanorobots be the next big cancer-fighting tool? Researchers from Chonnam National University in Gwangju, South Korea have created so-called “Bacteriobot,” a genetically-modified non-toxic salmonella bacteria that delivers cancer treatments that target tumors.
The bacteria is attracted to chemicals released by cancer cells. The Bacteriobot then goes directly to the tumors and releases the medication stored inside, attacking the problem areas. Traditional cancer treatments often wreak havoc on healthy tissues and other internal organs, so any treatment that can target just the tumors while sparing other tissue is highly sought after.
“First of all, the main feature of Bacteriobot is that the robot has a sensing function to diagnose the cancer, and it’s attacking the cancer itself as it uses the bacteria’s brain while moving toward the tumor region with its flagella,” Park Jong-Oh, director of robot research initiative at Chonnam National University, told Reuters.
Nanorobots in medicine isn’t an entirely new approach. CNET reported that Duke researchers were able to create a nanorobot called a “DNA nanocage” that could hold and release a biomolecule as well.
