ALB and neoplasm: The synergistic anti‐tumor effect of IR‐TAM@Alb was further validated through colony formation assay, showing that the combination of IR‐TAM@Alb and RT exhibited a synergistic effect greater than the sum of their individual effects with the sensitizing enhancement ratios (SER50) of ≈1.56 (Figure 3K,L; Figure S16, Supporting Information).
