Current Status and Future Prospects on Nanodelivery Systems Targeting the Small Intestine for Absorption of Bioactive...

Area of Science:

• Biomaterials Science
• Pharmacology
• Gastroenterology

Background:

• Bioactive substances often have poor solubility and stability, limiting their effectiveness.
• The gastrointestinal tract presents multiple barriers (acid, enzymes, mucus, cells) that hinder absorption.
• Existing nanodelivery systems may not fully address all gastrointestinal challenges.

Purpose of the Study:

• To review targeted nanodelivery systems for overcoming gastrointestinal barriers.
• To summarize strategies for designing nanodelivery systems that target the small intestine.
• To propose active targeted nanodelivery systems for enterocyte targeting as an ideal approach.

Main Methods:

• Literature review focusing on nanodelivery systems and gastrointestinal barriers.
• Analysis of strategies for enhancing stability and targeting within the GI tract.
• Discussion of active targeting mechanisms for enterocyte delivery.

Main Results:

• Targeted nanodelivery systems significantly improve bioactive substance bioavailability.
• Addressing all GI barriers is crucial for effective nanodelivery.
• Active targeted nanodelivery systems offer superior potential for enhancing absorption.

Conclusions:

• The ideal nanodelivery system actively targets enterocytes in the small intestine.
• Rational design of nanodelivery platforms is key for efficient bioactive substance absorption.
• This approach has implications for personalized nutrition and nutritional interventions.
