| Abstract: |
Systemic drug administration often causes off-target effects, limiting the efficacy of advanced therapies. Targeted drug delivery approaches increase local drug concentrations at the diseased site while minimizing systemic drug exposure. We present a magnetically guided microrobotic drug delivery platform capable of precise navigation under physiological conditions. This platform integrates a clinical electromagnetic navigation system, a custom-designed release catheter, and a dissolvable capsule for accurate therapeutic delivery. In vitro tests showed precise navigation in human vasculature models, and in vivo experiments confirmed tracking under fluoroscopy and successful navigation in large animal models. The microrobot balances magnetic material concentration, contrast agent loading, and therapeutic drug capacity, offering a promising solution for precise targeted drug delivery. Editor's summary: A challenge in the design of microrobots is balancing biocompatibility, biodegradability, size, and magnetic properties required for precise control. Ideally, one would also like to achieve real-time tracking, efficient navigation, and robust drug-loading capabilities. Landers et al. designed a microrobotic system that combines electromagnetic navigation, a release catheter, and dissolvable drug-loaded capsules. They demonstrated precise navigation in human vasculature models and tracking and navigation in large animal models. —Marc Lavine [ABSTRACT FROM AUTHOR] |
