Soon, small robots called “MANiACs” will be used for drug delivery. New research shows that when these tiny robots are managed using a magnetic field, they can reach the nerve tissues of the spinal cord and deliver the drug to precise locations. Coping with diseases of the central nervous system can be difficult.
Lamar Mayer “Oral or intravenous drug delivery to target cancers or neurological diseases may affect parts of the body and nervous system that are related to the disease,” said Lamar Mair of Weinberg Medical Physics. is not. Targeted drug delivery can increase effectiveness and reduce side effects.
One way to achieve a concentrated dose is to use small robots to get the drug to specific areas. Although this research is still in its infancy, researchers have developed various forms of microbots or millibots that may be able to meet this far-reaching goal. The most important problem with these robots is that they control their movement in body tissues.
Magnetic fields are a promising way to solve robots’ management problems, as they do not affect tissues and are usually safe. MANiAC robots are small robots that contain magnetic nanorods. This feature allows them to move in response to an externally applied magnetic field.
The researchers decided to test the MANiAC robots under conditions that may prevail in the body. These conditions also include the tortuous structure of the nervous system in which cerebrospinal fluid flows.
The researchers tested the flexibility of MANiAC robots to move up and down through the cerebrospinal fluid. To test the robots’ skills, they tested them on rat brain and mouse spinal cord. Experiments suggest that he may one day be able to use these robots as a substitute for medicine.
The study was published in the journal Frontiers in Robotics and AI.
