1,2 Ionization is critical for volatilizing sample analytes into a gas-phase. This primer covers a range of options which often require complementary equipment, such as syringe pumps, for efficient ...

Of these, one very promising technique has already gained much interest in the research community: matrix-assisted laser desorption/ionization (MALDI) molecular imaging. For easy and successful ...

SELDI-TOF-MS can be considered as an extension of the matrix-assisted laser desorption/ionization (MALDI)-TOF-MS method. In both cases, proteins to be analyzed are cocrystallized with UV-absorbing ...

My research group at Drexel has focused on improving three broad areas in the analysis of biological and synthetic polymer systems using mass spectrometry: 1) understanding fundamentals of the ...

Single-cell MALDI mass spectrometry (MS) imaging resolution is currently limited by the size of laser spot diameter, matrix crystal size/homogeneity, displacement of analytes during matrix ...
