Summary, etc. <p><span>Maghemite (γ-Fe</span><span>2</span><span>O</span><span>3</span><span>) nanoparticles were prepared using chemical synthesis method and used for sensing the hydrogen peroxide. The morphology of the γ-Fe</span><span>2</span><span>O</span><span>3</span><span> nanoparticles was characterized by scanning electron microscopy. The γ-Fe</span><span>2</span><span>O</span><span>3</span><span> nanoparticles were used to modify glassy carbon electrode (GCE) to form nano γ-Fe</span><span>2</span><span>O</span><span>3</span><span> modified GC electrode for electrochemical sensing of hydrogen peroxide (H</span><span>2</span><span>O</span><span>2</span><span>). A potential controlled cyclic voltammetric (CV) technique was performed to sense hydrogen peroxide using nano γ-Fe</span><span>2</span><span>O</span><span>3</span><span> modified GC electrode. The nano γ-Fe</span><span>2</span><span>O</span><span>3</span><span> modified GC electrode showed excellent electrocatalytic ability towards H</span><span>2</span><span>O</span><span>2 </span><span>in 0.1M KCl supporting electrolyte. A significant enhancement in anodic peak current was observed for the nano γ-Fe</span><span>2</span><span>O</span><span>3</span><span> modified GC electrode than those of bare electrode. The electrochemical characteristics of hydrogen peroxide on nano γ-Fe</span><span>2</span><span>O</span><span>3</span><span> modified GC electrode  had been explored in this research communication.</span></p>
