Desorption electrospray ionization mass spectrometry reveals lipid metabolism of individual oocytes and embryos. [PDF]
Alteration of maternal lipid metabolism early in development has been shown to trigger obesity, insulin resistance, type 2 diabetes and cardiovascular diseases later in life in humans and animal models. Here, we set out to determine (i) lipid composition

Internal energy distributions in desorption electrospray ionization (DESI) [PDF]
The internal energy distributions of typical ions generated by desorption electrospray ionization (DESI) were measured using the "survival yield" method, and compared with corresponding data for electrospray ionization (ESI) and electrosonic spray ionization (ESSI).
