MALDI Imaging Through Laser-Induced Post-Ionization Pushes the Boundaries of Pharmaceutical Development Studies

Florian Barré (Presenter)

Presenter Bio(s): I obtained a bachelor specialized in cell biology and physiology that I got at Lille 1 University in France. I graduated with honors in 2015 with a Proteomics master that I also got at Lille 1 University with Isabelle Fournier and Michel Salzet as directors of the master. During my master, I went to Copenhagen at BRIC institute for 6 months for my first year internship where my project was to create luminescent and fluorescent cancer cell lines in Lund Anders’s laboratory. For my second year of master I went to Uppsala University, at Per Andrén’s laboratory for a project concerning the quantitation of a drug in the brain by MSI coupled to LC-MS for 6 months as well.
Afterwards, Ron Heeren and Berta Cillero-Pastor offered me the opportunity to work on cartilage regeneration within a Marie Curie consortium. During PhD, I tried to be involved in the MSI community. For this reason, I was p

Drug imaging is one of the major mass spectrometry imaging (MSI) applications. However, drug development through MSI has some limitations. Indeed, some compounds are not easily detectable due to poor ionization efficiency and ion suppression effects. In this work, we used post-ionization matrix assisted laser desorption/ionization (MALDI-2) to overcome these problems and we are showing that 80% of the drugs we tested directly benefit from ionization enhancement. We are now able to detect pharmaceuticals that are non-detectable by conventional MALDI pushing the boundaries of MSI for drug studies.
