Micro/nanorobots for gastrointestinal tract.

Area of Science:

• Nanotechnology and Biomedical Engineering
• Gastroenterology
• Drug Delivery Systems

Background:

• Gastrointestinal diseases pose significant challenges in treatment and drug delivery.
• Current therapies often suffer from low bioavailability and systemic side effects.
• Micro/nanomotors (MNMs) represent an emerging frontier in targeted gastrointestinal therapies.

Purpose of the Study:

• To review the current state of micro/nanomotors (MNMs) for gastrointestinal applications.
• To summarize MNM classifications, power sources, and therapeutic potential.
• To provide insights for future development in treating gastrointestinal diseases using MNMs.

Main Methods:

• Literature review of micro/nanomotor technology and its application in the gastrointestinal tract.
• Analysis of MNM capabilities, including oral administration, mucosal traversal, and targeted delivery.
• Examination of stimulus-responsive drug release mechanisms.

Main Results:

• MNMs can be orally administered and navigate the gastrointestinal tract.
• They effectively traverse mucosal layers and tissue barriers to reach lesion sites.
• Targeted drug delivery by MNMs enhances bioavailability and therapeutic effects while minimizing side effects.

Conclusions:

• Micro/nanomotors show significant promise for revolutionizing gastrointestinal disease treatment.
• Their ability for precise, targeted drug delivery offers improved efficacy and safety.
• Further research into MNM design and application will drive innovation in gastroenterology.
