摘要：
Carbohydrate biotemplates of glucose (C6H12O6) and starch (C6H12O6)(n) in to Zinc oxide (ZnO) nano thin films (NTFs) prepared for enhanced antibacterial activity by Successive Ionic Layer Adsorption Reaction (SILAR). X-ray diffraction (XRD) patterns revealed that the crystalline size values were decreased by the incorporation of carbohydrate molecules. Scanning electron microscope (SEM) and Field emission scanning electron microscope (FESEM) confirmed that the different morphologies by the addition of glucose and starch. The interactions of carbohydrate molecules with ZnO were identified by using FTIR and EDAX. Energy band gap of samples was calculated by UV absorption spectra. The emission property of Zinc oxide, Glucose/ZnO and Starch/ZnO was studied by photoluminescence (PL) spectra. The antibacterial activity of carbohydrate biotemplates (Cbts-ZnO) results showed that enhanced effect than pure ZnO for the selected pathogenic bacteria's. (C) 2017 Elsevier Ltd.
