In this paper, ultralong MnOOH nanowires were first synthesized via a facile solution method without using any organic surfactants. A novel non-enzymatic hydrogen peroxide (H2O2) sensor was then developed on the base of MnOOH nanowire composite film modified glass carbon electrode (GCE). The resulted biosensor exhibited excellent performance for H2O2 determination with a wide linear range (1.5 x 10(-4)-1.6 mM), a highly reproducible response (R.S.D. of 2.7%) and long-term stability. The good analytical performance, low cost and straightforward preparation method made this novel electrode material promising for the development of effective non-enzymatic hydrogen peroxide sensor.
