ALB and neoplasm: Then, to better decrease the dosage of TAM needed for RT sensitization and enhance its tumor‐targeting capacity, TAM was chemically conjugated with tumor‐targeting heptamethine cyanine dye IR‐68 to establish novel TAM derivate named IR‐TAM and then further self‐assembled with Alb to form IR‐TAM@Alb nanoparticles (Figures 1 and 2).
