With the specific reaction between PBA and sialic acid, which is overexpressed in many kinds of cancer cells, PBA has been used as a targeting moiety for tumortargeting drug delivery. Additionally, PBA as an electron acceptor affords nanomaterials Lewis acid-base coordination with electron donor atoms such as nitrogen and oxygen, which can be exploited for developing drug delivery systems with high drug loading. Furthermore, PBA-containing materials can stoichiometric consume reactive oxygen species(ROS) and show a nucleus targeting ability. This current review outlined PBA-containing biomaterials with various responsive abilities including sialic acid-targeting, sugars-binding, ROS-response, ATP-response, dopamine-binding, and nuclear targeting. On this basis, their biomedical applications were summarized.展开更多
