The MOF-Microbiome Axis: a New Paradigm for Precision Nanomedicine

The gut microbiome is crucial for human health, and its imbalance, known as dysbiosis, is associated with diseases such as inflammatory bowel disease, metabolic disorders, and neurological disorders. Traditional treatments, such as probiotics and fecal microbiota transplants, often lack precision, making the emerging field of nanomedicine a promising alternative. This review introduces the "MOF-Microbiome Axis," which explores the interactions between metal-organic frameworks (MOFs), versatile, porous materials, and the gut microbiome. It focuses on designing gastrointestinal-targeted MOFs that are biocompatible and responsive to stimuli. We discuss how MOFs can serve as scaffolds, controlled-release vehicles, and metabolite scavengers, highlighting their therapeutic applications in targeted antimicrobial therapy, enhanced probiotic delivery, and immunomodulation. The review also addresses important challenges in biosafety, scalable production, and personalized treatment, suggesting future directions such as bio-hybrid systems and precision microbiome editing. Overall, the MOF-Microbiome Axis offers a new perspective on microbiome engineering and advanced therapeutic approaches.
