Investigating the viability of electrodeposited vanadium pentoxide as a suitable electrode material for in vivo amperometric hydrogen sulfide detection

► V2O5 is assessed as a potential material for in vivo H2S detection. ► V2O5 showed a quick and linear response over a range of 0.5 - 15 μM H2S. ► NO and CO interfered with selective H2S oxidation.
