E-MALDI: Optimized conditions during electrowetting-enhanced drop drying for MALDI-MS

We recently showed that electrowetting-enhanced sample preparation for MALDI-MS (eMALDI) can increase the intensity of the MALDI signal by 2-25 times compared to conventional drop drying by concentrating all the dried sample in a single spot rather than leaving behind a heterogeneous coffee stain pattern. Here, we demonstrate that the eMALDI...
