Reading Abstract
A team of scientists in Singapore has developed a micro-sized intelligent robot, the size of a grain of rice, controlled by a micro-magnetic field, capable of targeted drug delivery within the body.
This micro soft robot is made from non-toxic intelligent magnetic composite materials, highly flexible, and can “navigate” through complex environments in the body, demonstrating potential for precise drug delivery.
The micro robot can carry up to four different drugs and release drug components accurately according to a programmed sequence. Compared to traditional drug delivery methods (such as oral or injection), the micro robot is expected to enhance precision efficacy and reduce side effects. In the field of cancer precision therapy, there is an urgent need for precise control of multiple drug combination treatments to achieve optimal efficacy.
In simulated experiments, the micro soft robot demonstrated the ability to effectively deliver drugs through different microenvironments, even functioning normally in thicker liquids, while controlling drug release precisely to avoid excessive leakage.
The research team plans to further reduce the size of the robot in the future, hoping to apply it soon in clinical treatments for malignant tumors, including brain tumors and bladder cancer.
Industry experts comment that this micro robot technology opens up new possibilities for targeted drug delivery technology and is expected to bring breakthrough advances in minimally invasive surgery and precision medicine. It is worth noting.
