Several medical diagnostic pathways of nanomaterials on intestinal diseases. A The EPR effect is formed by the increased permeability of the vascular epithelial cells at the site of inflammation, and the nanomaterials can be targeted for precise detection. B Highly sensitive nanomaterials detect circulating cancer cells in the blood of cancer patients. C Nanomaterials specific detection of tumor cell surface markers
