Highly sensitive and selective electrochemical detection of caffeine, theophylline and guaiacol in green tea, green coffee, coffee, and tea extracts using a SnS₂ nanoflake-modified electrode

Abstract

In the present work, SnS2 nanostructures (TS) with different morphology have been synthesized in three different solvents, Milli-Q water (W), ethanol (E) and isopropanol (I) using a simple solvothermal method....
