Electrochemical Determination of Gallic Acid in Tea Samples Using Pyramidal Pt Nanoparticles

Advanced Electronic Materials, EarlyView.
A novel electrochemical sensor based on pyramidal Pt nanoparticles for gallic acid detection in black and green tea samples is developed. The sensor is prepared by a simple drop casting of nanoparticles on the electrode surface, without any supporting materials, such as polymer matrices and surfactants.
