We are developing mass spectrometric imaging technique to analyze plant metabolites in single cell level. With this new technique, we can reveal unprecedented details of plant metabolism.
We are using top-notch instrumentation for this project, matrix-assisted laser desorption ionization (MALDI)-linear ion trap-orbitrap mass spectrometer. By reducing the laser beam size down to 10um size, we can probe molecules present in very narrow area, and acquire high-resolution mass spectra for over thousands of x and y positions.
Knowledge on instrumental analysis is recommended but not required. Students will learn about mass spectrometry and bioanalytical chemistry technique that may be useful in their career.
