Qualitative and quantitative analysis of chlorpyrifos residues in tea by surface-enhanced Raman spectroscopy (SERS) combined with chemometric models

Zhu, J.; Agyekum, A. A.; Kutsanedzie, F. Y.; Li, H.; Chen, Q.; Ouyang, Q.; Jiang, H. (Lwt – Food Science and Technology, 2018)

Surface-enhanced Raman spectroscopy (SERS) combined with chemometric models were employed to develop a rapid, low-cost, and sensitive method for qualitative and quantitative analysis of chlorpyrifos residues in tea. Au@Ag ...
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 ...
