Nylon nanoweb with TiO₂ nanoparticles as a solid matrix for matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry

Abstract

The nylon nanoweb with TiO(2) particles can be applied for the detection of volatile small molecule analytes in the m/z ratio range of small molecules.

Laser‐Induced Surface Reconstruction of Nanoporous Au‐Modified TiO2 Nanowires for In Situ Performance Enhancement in Desorption and Ionization Mass Spectrometry

“…Randomly oriented TNW was first prepared via a wet‐corrosion method through a three‐step process of alkali, water, and heat treatment, as previously reported. [ 25,26 ] Then, the as‐synthesized TNWs were modified with nanoporous Au (npAu) by alloying and dealloying processes as follows: [ 27,28 ] 1) Thin Au and Ag layers were sequentially deposited on the TNW and thermally dewetted via atomic surface diffusion to minimize their surface energy during heat treatment considerably below their melting temperatures (solid‐state dewetting). Thus, the thin bilayers of Au and Ag transformed into AuAg alloy nanoislands in which Au and Ag were randomly positioned.…”

“…Further, various types of TiO 2 nanostructures have been used for LDI‐MS, including nanotubes, nanowires, and nanoparticles. [ 6,25,26 ]…”

Nanomaterials as Assisted Matrix of Laser Desorption/Ionization Time-of-Flight Mass Spectrometry for the Analysis of Small Molecules

“…Among various metal-or metal oxide-based nanomaterials (e.g., Au [51,52,53,54,55], Ag [56], Pt [57,58,59], TiO 2 [60,61,62], ZnO [63], CdS [64], and HgTe [65] NPs) that explored as matrices for LDI-TOF MS, TiO 2 and gold NPs (Au NPs) attracted much more attention because their intrinsic advantages, such as large surface area, strong absorption efficiency in UV-visible region, high chemical stability, easy modification and preparation.…”

Humic acids as both matrix for matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and adsorbent for magnetic solid phase extraction

“…In addition, numerous materials with different composition and morphology like polymer film [3,7,9,14,15], porous silicon [16e18], metal or metal oxide nanoparticles [19,20], carbon-based materials [8,21e26] etc. were also employed to reduce the matrix interference in the mass region of interest.…”
