Figure 4. Schematic diagram of hydrogel-based tumor visualization imaging and image-guided modalities. The hydrogel network confines the retention of imaging components and can integrate with the TME to confer smart responsive properties, enabling tumor visualization and the reflection or prediction of therapeutic outcomes [Created in BioRender. Mao, X. (2026) https://BioRender.com/4kts57u]. TME: Tumor microenvironment; ATP: adenosine triphosphate; NIR: near-infrared.
