Grain-Sized Soft Robots Offer Precision Drug Delivery Revolution

NTU Singapore researchers develop innovative robots that navigate the body to deliver multiple drugs with unprecedented accuracy.

Engineers at Nanyang Technological University, Singapore, have created miniature robots that can carry and release up to four different drugs in programmable sequences.
These soft robots are controlled by magnetic fields, allowing them to navigate complex environments within the human body with high dexterity.
The robots are made from non-toxic magnetic composite materials, ensuring safety and biocompatibility for potential medical applications.
Lab experiments demonstrated the robots' ability to release drugs in controlled manners over eight hours, with minimal leakage, highlighting their potential for precise therapies.
The research team aims to further miniaturize the robots for treatments of conditions like brain tumors and cancers, with future tests planned on organ-on-chip devices and animal models.
