Summary, etc. <p class="Abstract">A non-enzymatic electrochemical sensor for hydrogen peroxide based on silver nanoparticle (AgNP) modified platinum electrode has been fabricated by multiple cyclic voltammetric scan of platinum electrode in AgNP solution in aqueous medium. The modified electrode (Pt/AgNP) can detect hydrogen peroxide in aqueous medium, bovine serum albumin  and live L6 rat myoblast cells with high sensitivity and selectivity by cyclic voltammetry and electrochemical impedance spectroscopy. The limit of detection of Pt/AgNP towards H<sub>2</sub>O<sub>2</sub> is 5.4×10<sup>-7</sup> M. The detection of H<sub>2</sub>O<sub>2</sub> by Pt/AgNP is free of interference from Na<sup>+</sup>, K<sup>+</sup>, Ca<sup>2+</sup>, Mg<sup>2+</sup>, dopamine and ascorbic acid.</p>
