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.
