Magnetic Microrobots: A Novel Approach for Drug Delivery

Magnetic microrobots are perfect for biological detection and targeted delivery because of their small size, variety of functional structures, and precision control features. The two primary categories of microrobots are bioinspired and biohybrid designs, while there are numerous more varieties. Red blood cell-based microrobots, bacteria-and microalgae-based microrobots and exosome-based microrobots are recently introduced magnetic microrobots. Magnetic fields are the most popular control technique for microrobots. In addition to aiding precise navigation, external magnetic fields can also provide secondary functions, such as piezoelectric effects, electromagnetic stimulation, and hyperthermia. Magnetically steered microrobots are used in many different applications due to their unique capabilities and small size. Microrobots can improve therapeutic efficacy and reduce side effects by delivering drugs to specific parts of the body. This microrobot's ability to decompose into non-toxic substances under certain conditions is another advantage for targeted distribution.
