WFDC2 and ovarian carcinoma: Han et al. [167] in their work described a dual-modal fluorescence/MR nanoprobe with carbon nanoparticles combined with manganese and nitrogen (Mn-N-CNSs) and conjugated to an anti-HE4 monoclonal antibody (Mn-N-CNSs @ anti-HE4) that can be used in the diagnosis of ovarian cancer cells.
