an ionization platform was developed for the ultrasensitive detection of molecules. With detection limits down to the zeptomolar range (a thousand trillionth of a mole,

however, matrix-assisted laser desorption ionization (MALDI) mass spectrometry techniques suffer from matrix-associated background problems that prevent the detection of small molecules at individual cell levels.

This process causes the ionization of cellular molecules without the hassle of a matrix. Using NAPA mass spectrometry

and xenobiotics in a broad class of samples, making it the foundation for matrix-free laser desorption ionization.

#Nanopost Array Nanotechnology in REDICHIP Enables Rapid Identification of Small Molecules in Biofluids Known as REDICHIP#("Resonance-Enhanced Desorption Ionization),

and in the process of ionization towards the plasma a air begins to emit light. To achieve this effect allowed the femtosecond laser pulse

and data obtained with matrix-assisted laser desorption/ionization (MALDI) chemical imaging analyses of serial sections of the same tissue.

and it cannot be applied for the inspection of foods that have lactic acid bacteria because X-ray radiation causes ionization of such foods.

As detailed in Rapid Communications in Mass Spectrometry, they validated the instrument--a laser ablation resonance ionization mass spectrometer--by dating a rock from Mars:

Polyu researchers have developed a simplified method for direct analysis of edible oils using matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS). In the new MALDI-MS

While yet other mass spectrometry-based techniques such as desorption electrospray ionization and rapid evaporative ionization mass spectrometry are being evaluated for classifying tumors and providing prognostic information,
