Ferritin-based FAP-α-responsive fluorescence nanoprobes could be activated immediately as they penetrate the tumor blood vessels and come across the FAP-α molecules on the membrane of CAFs in the tumor microenvironment instead of reaching a certain depth into tumor tissue to interact with tumor cells. This probe may become a promising nanomaterial for highly specific and sensitive tumor imaging through responding to the enzymes in the tumor microenvironment.
