The Gastrointestinal Tract: A Unique Battlefield for Bioengineering Delivery Platforms

Area of Science:

• Gastroenterology and Bioengineering
• Biomaterials and Drug Delivery Systems

Background:

• Traditional oral and systemic drug delivery for gastrointestinal diseases face challenges like degradation, poor absorption, and toxicity, leading to low bioavailability.
• Localized gastrointestinal conditions, including inflammation and early-stage cancers, require targeted therapies for improved efficacy and reduced side effects.

Purpose of the Study:

• To review the integration of advanced bioengineering platforms with therapeutic gastrointestinal endoscopy for improved drug delivery.
• To explore nanoparticle systems, in situ-forming hydrogels, and drug-eluting stents as key bioengineered platforms.
• To discuss strategies for enhancing spatial precision, such as active targeting and stimulus-responsive release.

Main Methods:

• Review of literature on bioengineered platforms and their application in gastrointestinal endoscopy.
• Analysis of nanoparticle systems, hydrogels, and stents for localized drug delivery.
• Investigation of advanced targeting and release mechanisms for precision therapy.

Main Results:

• The synergy between bioengineering platforms and endoscopy enables precise, minimally invasive, and sustained local therapy.
• Nanoparticles, hydrogels, and stents offer versatile solutions for localized chemotherapy, wound management, and sustained drug release.
• Advanced strategies like active targeting improve spatial precision in drug delivery.

Conclusions:

• The convergence of bioengineering and endoscopy holds significant potential for transforming gastrointestinal disease treatment.
• This approach promises a new era of precise, localized, and sustained micro-invasive therapies.
• Clinical translation requires addressing challenges in biocompatibility, manufacturing, regulation, and cost-effectiveness.
