We utilized Gal1 as a molecular target and DMSA-Fe3O4 nanoparticles as a probe for early stage pancreatic tumor detection with an MTAI schematically shown in Figure 1A. DMSA-Fe3O4 nanoparticles were labeled with a Gal1 antibody to construct anti-Gal1-Fe3O4 (Figure 1B). The gene discussed is LGALS1; the disease is pancreatic neoplasm.
