Iron‐Tannic Acid Hydrogel Mediated Mild Photothermal Therapy Combined With Ferroptosis Enhances Anti‐Tumor Immunity in Colorectal Cancer
ABSTRACT Postoperative recurrence and metastasis are the primary causes of mortality in colorectal cancer (CRC). And its immunosuppressive tumor microenvironment (TME) often results in the poor response to immune checkpoint blockade (ICB). This study designed an injectable and adhesive tannic acid‐iron hydrogel for loc...
