rGO-NS SERS-based coupled chemometric prediction of acetamiprid residue in green tea.

Hassan, M. M.; Chen, Q.; Kutsanedzie, F. Y.; Li, H.; Zareef, M.; Xu, Y.; Agyekum, A. A. (Journal of Food and Drug Analysis, 2019)

Pesticide residue in food is of grave concern in recent years. In this paper, a rapid, sensitive, SERS (Surface-enhanced Raman scattering) active reduced-graphene-oxide-gold-nano-star (rGO-NS) nano-composite nanosensor was ...
Viswadevarayalu, A. (2019). Fast sensing of imidacloprid residue in tea using surface-enhanced Raman scattering by comparative multivariate calibration

Chen, Q.; Hassan, M. M.; Xu, J.; Zareef, M.; Li, H.; Xu, Y.; Kutsanedzie, F. Y.; Viswadevarayalu, A. (Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2019)

This study focused on the fabrication of a rapid, highly sensitive and inexpensive technique for the quantification of imidacloprid residue in green tea, based on surface-enhanced Raman scattering (SERS) using highly ...
