A Frustrating Medical Issue is Solved


It’s not so rare that patients are forced to go back to hospital with post-surgery infections. The recurring infections after inducting a medical implant in the body is a frustrating medical challenge. The major cause is Biofilm, which comprises disease-causing bacteria and other microorganisms. It is a slimy substance that can grow in medical implants inside patients. The World Health Organization has labeled antimicrobial resistance as a “major threat to human health with significant global economic and security implications.”

Researchers from the Chinese University of Hong Kong (CUHK) have now found a way to tackle this issue. They have developed a microrobot powered by magnets that can remove build-ups of dangerous bacteria inside medical devices and minimize the risk of infections linked to implants in patients. The robot is designed to cut the risk of infections by removing Biofilm from inside medical devices such as catheters and stents. The researchers proclaim that the robot can remove the substance, linked to more than 80 percent of infections in humans, with fewer side effects compared with other methods.

The CUHK, which was It was founded in 1963 as a federation of three existing colleges – Chung Chi College, New Asia College and United College. The oldest among them, New Asia College was established in 1949 by anti-Communist Confucian scholars from Mainland China. The CUHK is home to global leaders from all walks of life, and this special issue is a dedication to each of them. Do let us know your thoughts.
