Final answer:
Anti-dig Fab fragments are antibody fragments used in nanomedicine to functionalize the surface of nanodelivery systems.
Step-by-step explanation:
The term Anti-dig Fab fragments refers to antibody fragments that are engineered for functionalizing the surface of nanodelivery systems in nanomedicine. These fragments include Fab fragments, which are antibody fragments that retain the antigen binding capacity of the intact antibody molecule.
