Armored probiotics for oral delivery.

Area of Science:

• Microbiology
• Biomaterials Science
• Gastroenterology

Background:

• Probiotics are beneficial intestinal flora regulators with therapeutic potential.
• Oral probiotics face challenges in the gastrointestinal tract, leading to low survival and efficacy.
• Functional biomaterials offer a strategy to protect and enhance probiotic delivery.

Purpose of the Study:

• To review challenges faced by oral probiotics.
• To discuss the research progress of armored probiotics delivery systems.
• To analyze the applications and future trends of armored probiotics in disease treatment.

Main Methods:

• Systematic review of scientific literature.
• Focus on functional biomaterials used as protective 'armors' for probiotics.
• Analysis of how these armors overcome gastrointestinal obstacles and improve delivery efficiency.

Main Results:

• Various functional armors effectively protect probiotics from harsh gastrointestinal conditions.
• Armored probiotics demonstrate enhanced survival rates and therapeutic efficacy.
• Diverse applications of armored probiotics in treating various diseases have been identified.

Conclusions:

• Armored probiotics represent a significant advancement in oral delivery systems.
• Functional biomaterials are key to overcoming the limitations of traditional probiotic therapies.
• Future research trends point towards developing sophisticated probiotics-based therapies with improved clinical outcomes.
