Microswimmer Robots in Cardiovascular Therapies
Cardiovascular diseases (CVDs) remain the leading cause of death worldwide[1] Untethered microscale robots (“microswimmers”) have emerged as a promising class of minimally invasive tools for addressing vascular pathologies. These tiny devices often magnetically actuated can navigate the bloodstream and reach sites of interest (e.g. arterial blockages) that are inaccessible by conventional instruments. Researchers note their potential to targeted drug delivery , clot removal , and even plaque debridement in arteries [2]. For example, Microswimmers can carry and release therapeutics at precise locations to improve efficacy while reducing side effects [3]. They can also be designed to mechanically clear obstructions: e.g. rotating magnetic helices could “scrape” lipid-rich plaque from vessel walls…
