Treating rheumatoid arthritis with micromotors
Rheumatoid arthritis is a chronic inflammatory disorder marked by joint pain, swelling and damage. Although medications, such as steroids, anti-inflammatory drugs and immunosuppressants, can help slow joint destruction and relieve pain, they have side effects and aren’t completely successful. Now, researchers have developed magnesium-based micromotors propelled by hydrogen bubbles, which improved rheumatoid arthritis symptoms when injected into the joints of rats.
