Synthesis of zinc oxide nanorods on platinum wire & fabrication of triglyceride biosensor

In the present study platinum (Pt) wire has been used as a substrate for the synthesis of zinc oxide nanorods. Aqueous Chemical Growth method has been used for the successful synthesis of ZnO nanorods on the platinum wire. The synthesis has been confirmed by various analytical techniques. The characterization has also been done by UV-Vis Spectroscopy, X-Ray Diffraction (XRD), Field Effect Scanning Electron Microscopy (FESEM), Fourier Transform Infrared Spectroscopy (FTIR) and Electrochemical Impedance Study (EIS). The above said characterization techniques confirmed the optical, structural constituency, bending vibrations of bond formation and electrical conductivity of the synthesized nanorods. The newly developed biosensor showed linearity ranging from 10 μM to 250 μM with a minimum detection limit of 10 μM. This method also showed a good correlation coefficient (r) 0.983.
