Research Interests

Our main focus lies in the development and applications of miniaturized, solvent-minimized sample preparation procedures in combination with chromatography. A primary objective is to apply these methods particularly to the analysis of contaminants of emerging concern. Our present interest includes the development of seamless, integrated automated analytical platforms for water quality monitoring applications

 

Research Highlight

Ref.: Tang, S. et al, Smartphone Nanocolorimetric Determination of Hydrogen Sulfide in Biosamples after Silver–Gold Core–Shell Nanoprism-Based Headspace Single-Drop Microextraction. Anal. Chem, 2019, 91, 5888-5895. This paper describes the development of a sensitive procedure for the silver-gold core-shell nanoprism-based single-drop microextraction of hydrogen sulfide from spoiled egg and milk, followed by analysis using a smartphone as a nano-colorimetric tool.
