Zhu et al. [93] designed a multifunctional theranostic NP (NMOFs@BSA/SDs@MnO2) with nanoscale metal organic frameworks (NMOFs, composed of TCPP as ligand and Fe3+), bovine serum albumin (BSA) and sulfadiazines (SDs), to provide actively targeting for the over-expressed carbonic anhydrase IX (CA IX) in tumour cells, and MnO2. Here, CA9 is linked to neoplasm.
