Investigating the potential of ZTO as an efficient and cheap SERS substrate for the identification of bacteria

A very inexpensive and efficient SERS substrate based on ZTO nanostructures was fabricated using the thermal evaporation method.

The morphology and structure of grown ZTO nanostructures were further controlled by annealing the samples at different temperatures.

After structural and morphological characterization of these ZTO nanostructures, we have used them for detection of Ecoli and Methylene Blue (MB) with least concentrations of 0.01, 0.05, 0.1, 0.2, and 0.3M using a Raman spectrometer.

The observed results demonstrated that controlled ZTO nanostructures could be the potential candidates for the detection of various pathogens in the near future.
