Femtosecond laser ablation for simultaneous atomization and ionization (fs-SAI) of large organic molecules
نویسندگان
چکیده
By applying the femtosecond laser ablation technique, we have simultaneously atomized and ionized large organic molecules on a solid substrate. This observation is in contrast with the photoionization of cyclic aromatic hydrocarbons by femtosecond laser in the gas phase where little fragmentation has been observed. Our result will promote the development of single-shot chemical analyses of isotope-labeled large organic molecules.

Influence of laser parameters and staining on femtosecond laser-based intracellular nanosurgery
Femtosecond (fs) laser-based intracellular nanosurgery has become an important tool in cell biology, albeit the mechanisms in the so-called low-density plasma regime are largely unknown. Previous calculations of free-electron densities for intracellular surgery used water as a model substance for biological media and neglected the presence of dye and biomolecules. In addition, it is still uncle...

Intact, nonvolatile, biological macromolecules can be transferred directly from the solid state into the gas phase, in ambient air, for subsequent mass spectral analysis using non-resonant femtosecond (fs) laser desorption combined with electrospray ionization (ESI). Mass spectral measurements for neat samples, including a dipeptide, protoporphyrin IX and vitamin B12 adsorbed on a glass insulat...
متن کاملUltrafast Ionization and Fragmentation: From Small Molecules to Proteomic Analysis
Proteomic analysis offers great diagnostic relevance, because unlike DNA, different cells in an organism express different proteins. In fact, the cellular proteome can vary as a function of time or in response to stimuli. Beyond amino acid sequence, protein function depends on chemical modifications known as posttranslational modifications (PTMs) that serve as “switches” and “signals” that acti...
متن کاملStudy of laser ablation using nano-second laser pulses
In this paper, the laser ablation process based on the irradiation of nanosecond pulsed lasers on a copper target surface in the presence of Helium gas is studied. The dynamical behaviors of the generated plasma in the helium gas and evaporated copper at the atmospheric pressure are examined using a laser pulse, laser wavelength of and intensity of 7×1010W/cm2. A one-dimensional thermal model ...
متن کاملAnalysis of amphiphilic lipids and hydrophobic proteins using nonresonant femtosecond laser vaporization with electrospray post-ionization.
Amphiphilic lipids and hydrophobic proteins are vaporized at atmospheric pressure using nonresonant 70 femtosecond (fs) laser pulses followed by electrospray post-ionization prior to being transferred into a time-of-flight mass spectrometer for mass analysis. Measurements of molecules on metal and transparent dielectric surfaces indicate that vaporization occurs through a nonthermal mechanism. ...
