Dual-responsive micromotors pill for targeted retention in intestines in vivo

Recent advances in synthetic micro/nanomotors in numerous biofluids have garnered widespread hobby because of their capability biomedical programs. However, present micro/nanomotor systems for shipping inside the gastrointestinal (GI) tract are inefficient in propulsion. Here, we present a micromotor-tableted tablet that achieves lively retention in the GI tract in vivo. The drug-loaded magnesium-based totally absolutely Janus micromotors, enveloped in an enteric polymer-protected magnetic tablet, stay sturdy within the stomach. The movement of the micromotor tablets (MPs) is facilitated by means of the use of an outside low-frequency gradient magnetic difficulty, directing them to focused regions inside the intestines. A excessive-frequency alternating magnetic concern induces water-powered propulsion of the micromotors via the magnetocaloric effect, attaining lively retention in GI tissue. The integration of this newly evolved MP tool lets in energetic retention of micromotors in vivo, promising more suitable drug transport for GI treatment.
