The use of micro-robots for delivering drugs into specific areas of the body offers the possibility of targeting the regions with cancerous cells only, instead of spreading the drug all over the body. A serious restriction for reaching narrow vessels of the body is the size of the motor of micro-robot, which can be up to several millimeters.
The proposed solution by the researchers at Chonnam National University in South Korea in this patent application (US Patent App No: US 20110184388) is the use of bacteria as motors. The micro-robot is made of two parts:
1. The bacteria used as a motor.
2. A microstructure carrying the drug-injecting mechanism.
The bacteria move the micro-robot to the cancerous region, after which the microstructure can treat the disease by spraying the drug.
