摘要: A rapid, reproducible, cost-effective approaches for the detection of hydrogen peroxide has been developed based on change localized surface plasmon resonance (LSPR) peak Au nanorods (NRs). NRs were prepared by silver ion-assisted seed-mediated method, which are characterized UV-vis spectroscopy and transmission electron microscopy. The longitudinal band is highly sensitive to their aspect ratios so that LSPR was shift with ratios. Hydrogen (H(2)O(2)) high oxidation potential can decompose NRs. As a result, be shortened through an reaction H(2)O(2). After shortening NRs, peaks show blue shift. displays dependence spectral concentration It provides more simple method detecting
