Nanomedicine is one of the most promising fields in biomedicine. Inorganic
nanomaterials stand out among many
nanomaterials due to their excellent physicochemical properties, stable
chemical properties and high biocompatibility. As an inorganic
nanomaterial,
bismuth-based
nanomaterials have the advantages of adjustable band gap, low
toxicity, easy functionalization, large
X-ray attenuation coefficient, high photothermal conversion
efficiency and long cycle
half-life, so they have good promising application in
cancer diagnosis and
treatment. This
review summarizes the recent
research progress of
bismuth-based
nanomaterials in
tumor diagnosis,
treatment and
biosafety, which provides a theoretical basis for the design and exploitation of a new generation of
bismuth-based
nanomedicine systems.
