ALB and neoplasm: Wu and co‐workers used human serum albumin (HSA) as perfluorotributylamine (PFTBA, one of perfluorocarbons (PFCs)) carrier to construct perfluorotributylamine‐based albumin nanoparticles (PFTBA@HSA) (Figure 20f).[144] PFTBA may not only simultaneously increase drug delivery, but also relieve tumor hypoxia via effective platelet inhibition to disrupt tumor vessel barriers (Figure 20g), improving the antitumor efficacy of oxygen‐sensitive drugs.
