Tiny Robots Thinner Than a Human Hair Could Help Fight Cancer Tumours, Reveals Study

Scientists have developed special 3D-printed microbots, only 30 microns in diameter, capable of directly delivering drugs to cancer cells. These microbots can easily transition from solid to liquid and back, survive stomach acid, and are designed to pass out of the body in urine. Initial trials in mice have demonstrated their effectiveness in reducing the size of bladder tumours. Researcher Wei Gao from Caltech University highlighted the potential of these microbots for targeted drug delivery and precision surgery, expressing hope for future human trials. This innovative approach aims to enhance the efficiency and control of drug delivery to tumour sites, offering a promising platform for treating various conditions with different therapeutic agents.
