Identification Of Fungicide Thiram Using SERS

  • Fungicides are used for high productivity in farming.
  • Retained fungicides in soil/water is harmful.
  • Existing detection methods are time consuming and sophisticated    
  • In the current study, Thiram has been detected using SERS with 103 enhancement   
  • Surface-enhanced Raman spectroscopy (SERS) – high sensitivity, short detection time and nondestructive detection.

  • SERS shown enhanced Raman Signal

  • Detected minimum of 0.1 µM of Thiram on varying Concentration.

Conclusion

The vibration modes of Thiram were quickly identified by using SERS Technique.
