DAEJEON, May 21 (Korea Bizwire) – In a groundbreaking development, South Korean researchers have created a soft, biocompatible medical robot capable of real-time monitoring within the body before harmlessly dissolving upon completing its mission.
According to the National Research Foundation of Korea, a joint research team led by professor Go Gwangjun from Chosun University, the Korea Institute of Medical Microrobotics, and professor Choi Eunpyo from Chonnam National University has successfully developed this innovative technology.
The team’s ingenious design combines chitosan, a naturally occurring biodegradable polymer, with magnetic nanoparticles that respond to external magnetic fields. This unique combination allows the soft micromedical robot to navigate and be tracked to desired locations within the body.
By precisely etching microscopic patterns onto the robot’s surface, the researchers have enabled it to bend and flex in specific directions, mimicking the movements of flower petals, vines, or even human fingers. The magnetic nanoparticles facilitate controlled movement, guiding the robot to its intended target.
One of the remarkable features of this technology is its ability to biodegrade within four weeks without causing any toxicity or inflammatory responses, making it a safe and environmentally friendly solution for medical applications.
“This technology represents a groundbreaking achievement in the field of medical robotics, allowing for freely maneuverable robots that can harmlessly dissolve within the body without causing inflammation,” said Go. “We envision its potential applications in areas such as disease treatment and drug screening.”
The research findings were published in the prestigious scientific journal Advanced Functional Materials on April 23, showcasing the team’s pioneering work in the field of biomedical engineering.
As the medical community continues to explore innovative technologies to enhance patient care and treatment efficacy, these biodegradable medical robots offer a promising avenue for minimally invasive procedures, targeted drug delivery, and real-time monitoring of biological processes.
