Microfluidics-based fabrication and targeted motion control of multimodal therapeutic hydrogel capsule microrobots

under a magnetic field strength of 7.4 mT, thereby realizing millimeter-level positioning accuracy and complex curve trajectory tracking in vascular microchannels that simulate a blood environment. Experimental results indicate that the prepared multimodal hydrogel capsule microrobots possess excellent targeted movement capabilities, meeting the functional requirements for a synergistic "thermotherapy-chemotherapy" treatment, and demonstrate potential application in the development of low-toxicity, high-efficiency tumor combination therapy.
