a Change of the LSPR absorbance strength with time due to the introduction of 10–3 mol/L H2O2 solution in the as-synthesized Ag-NPs solution at a volume ratio 1:1.5; the inset shows the bubbles from H2O2 decomposition generated by the catalytic reaction between hydrogen peroxide and starch-stabilized Ag-NPs. b UV-vis absorption spectra recorded 15 min after the introduction of hydrogen peroxide solution with different concentrations in the solution of Ag-NPs at a volume ratio 1:1.5. c relevant photographs of Ag-NPs dispersions 60 min after the introduction of hydrogen peroxide with different concentrations [109]
