32941572-2	2020	In this article, biotinylated CD20 and CD3 antibodies were conjugated onto the surface of streptavidin modified ultra-small Fe3O4 nanoparticles via specific binding between streptavidin and biotin to construct a bi-specific nanoplatform (BSNP).	ferryl iron	124-129	keratin 20	Homo sapiens	30-34	
30787607-8	2019	Results: Cell targeting experiments and magnetic resonance (MR) signal and T2 measurements showed that the Fe3O4@DMSA@Ab nanoprobes have specific binding affinity for CD20-positive cells.	ferryl iron	107-112	keratin 20	Homo sapiens	167-171	
30787607-12	2019	Conclusion: These results indicate that Fe3O4@DMSA@Ab nanoprobes have the potential to serve as MRI tracers and therapeutic agents for CD20-positive cells.	ferryl iron	40-45	keratin 20	Homo sapiens	135-139
