The reaction of 2,3-diaminonaphthalene (DAN) with Se(IV) to form a fluorescent Se-DAN complex is the basis of a fluorometric method for determination of Se. With the aid of metabolically incorporated 75Se the method was critically re-examined. The study showed that

Current evidence suggests that two spatially distinct neuroanatomical networks, the dorsal attention network (DAN) and the default mode network (DMN), support externally and internally oriented cognition, respectively, and are functionally regulated by a third, frontoparietal control network (FPC). Interactions among

In this Communication, we report on the first preparation of conjugation polymer poly(2,3-diaminonaphthalene) (PDAN) microspheres via chemical oxidation polymerization of 2,3-diaminonaphthalene (DAN) monomers by ammonium persulfate (APS) at room temperature. We further demonstrate the use of PDAN microspheres as a
