Nanyang Technological UniversityOct 25 2024 A team of scientists at Nanyang Technological University, Singapore has developed grain-sized soft robots that can be controlled using magnetic fields for targeted drug delivery , paving the way to possible improved therapies in future.
Compared to earlier small-scale robots which can only carry up to three types of drugs and cannot be programmed for release in order, the newly developed miniature robots offer precision functions that have the potential to significantly improve therapeutic outcomes while minimising side effects, said the research team.
What was a scenario in a sci-fi movie is now becoming closer to reality with our lab's innovation. Traditional methods of drug delivery like oral administration and injections will seem comparatively inefficient when stacked up against sending a tiny robot through the body to deliver the drug exactly where it is needed.
The robot was first placed on a surface divided into four sections, and it succeeded in moving to each section at speeds of between 0.30 mm and 16.5 mm per second and releasing a different drug in each section, proving its ability to carry multiple drugs and to be programmable for their release in a controlled manner.
Co-authors of the study included Research Fellow Yang Zilin and PhD Graduate Xu Changyu from the School of MAE.
