Illustration of pH-sensitive degradable polymersomes based on PEG-PTMBPEC diblock copolymer for triggered release of both hydrophilic and hydrophobic anti-cancer drugs. In comparison, pH-sensitive degradable micelles are typically applied for the encapsulation and release of hydrophobic drugs only. (Reproduced from Ref. [129], with permission from Elsevier)
