Researchers at Max Planck Institute for Intelligent Systems situated in Germany have created bacterial microrobots that will deliver drug to tumour to eradicate it. The scientists explored bacteria’s tendency to incline more towards low pH areas, which are present near the premises of the tumour. Microrobots were made to enter the tumour and their movements were controlled by magnetic field to trigger anti-tumour drug. Due to certain characteristics such as high motility and tendency to gravitate towards low oxygen levels, bacteria can prove to be the best agents to battle off cancer, especially when they can be steered by the scientists in the area they desire.
