Background: There are enormous methods for modifying electrodes by Prussian blue analogues. We present here rather a very straight forward method of modification by noval nonelectrical deposition of PY nano thin film as a modifier ITO substrate.

Methods: PY film was deposited on ITO substrate by simply dipping it in liquid mixture solution of Fe+3 and Fe(CN)6-3 in water at (30C0) the resultant film was washed dried and characterized by XRD,AFM,UV and FTIR.

Results: Prepared PY films showed remarkable properties especially electro catalytic activity towards oxidation of AA, so the PY modified electrode was used as a sensor for AA with satisfactory sensitivity and practical linear range.

Conclusion: A new type of a nano PY film modified ITO electrode by very versatile and direct method by dip dry method, such PY film shows remarkable electrochemical properties and stability. PY film as a sensor offered a linear response to AA.
