Magnetically driven microrobots: Recent progress and future development

Multifunctional porous microspheres encapsulating oncolytic bacterial spores and their potential for cancer immunotherapy

“…With the use of an external magnetic field, the IONP-encapsulated microspheres can be remotely targeted to the disease site. [44][45][46] This targeted approach enables increased retention of the MPMs within the tumor, ensuring a more concentrated and localized delivery of the encapsulated therapeutic agents. As shown in Fig.…”

Lego-Microfluidics Generated Magnetically Responsive Bifunctional Microcapsules with Encapsulated Phase Change Material

“…To address these issues, microencapsulation has emerged as a prominent strategy involving the formation of core–shell structures composed of tiny droplets of PCMs encapsulated within a film-forming material . This approach effectively addresses the aforementioned challenges related to PCMs and enables applications of PCMs in diverse fields like construction materials, medicine, food packaging, thermo-regulated textiles, waste energy recovery, and electronics. − Particularly, PCM microcapsules with magnetic properties are being explored in various applications, including magnetically driven microrobots with thermal energy storage capability, PCMs with modular assembly and geometric conformality features, and infrared electromagnetic double shielding in electronic gadgets and military electronics . Zhuang et al developed magnetic PCM microcapsules with Fe 3 O 4 decorated acrylic copolymer shell and octadecane core using suspension polymerization.…”

Magnetically actuated hydrogel-based capsule microrobots for intravascular targeted drug delivery

“…21 Magnetic field driving modes of microrobots can be divided into three types: rotating magnetic field, 22 gradient magnetic field 23 and oscillating magnetic field. 24 These magnetic actuation methods have been proven to be safe and efficient, and it can drive the magnetic microrobots to accurately reach the target position through controllable actuation. 25,26 Based on the aforementioned controllable actuation of the microrobots and various model analyses for the transport of druggable particles in the microvasculature, 27,28 it is possible to realize the targeted drug delivery of the capsule microrobot in the blood vessel by magnetic actuation.…”
