Nanoporous molybdenum carbide nanowires: a novel sensing platform for DNA detection

Abstract

In this communication, a novel and highly sensitive DNA sensor based on nanoporous molybdenum carbide nanowires (Mo₂C NWs) is presented. The Mo₂C NWs were synthesized on a large scale via pyrolysis of a MoOx/amine hybrid precursor under an inert atmosphere. The enriched nanoporosity and the large active surface of these highly dispersed nanowires with uniform Mo₂C nanocrystallites make them an efficient nanosensor, leading to their high sensitivity with a detection limit of 50 pM and good selectivity.
