A novel technique for glucose sensing using collagen based thin film and zinc oxide (ZnO) nanoparticles, the Zinc Oxide Collagen Glucose Sensor (ZnOCGS) presented here. The Zinc oxide is synthesized using the two medium namely treating with 1.Ethanediol medium (Ethylene glycol) and 2.Water medium. It is characterized using the analytical techniques such as Fourier Transform infrared spectroscopy (FTIR) and Fourier Transform-Raman spectroscopy (FT-Raman). The FTIR spectra of the materials obtained from the synthesis of water medium shows the zinc oxide nanoparticles absorption band at 437cm-1. The spectrum obtained from Ethanediol (Ethylene glycol) also shows the same absorption peaks as in the water medium. The results obtained using FT-Raman spectroscopy also indicates the same absorption peaks in both the mediums.
