Great endeavors are undertaken to find effective nanoparticles to replace organic matrices for the analysis of small molecules using laser desorption ionization mass spectrometry (LDI-MS). Nanoparticles offer high sensitivity and better selectivity compared to conventional organic matrices. Surface assisted LDI-MS (SALDI-MS), and surface enhanced LDI-MS (SELDI-MS) provide clear background spectra without observable interferences peaks, and cause no fragmentation (soft ionization) of thermal and acidity labile molecules. This review article (with 460 references) summarizes the recent applications of nanoparticles including metallic, metal oxides, silicon, quantum dots, metal-organic frameworks and covalent organic frameworks, for the analysis of small molecules. Nanoparticles serve not only as surface for LDI-MS, but they can be also used as probe or pseudo-stationary phase for separation, enrichment, and microextraction. Hopefully, the knowledge and learning points gained from this review will deepen the understanding of nanoparticles applications for LDI-MS.

Three NO+-ruthenium(II) complexes were prepared by using cis-[RuCl2(DMSO)4] as precursor, P, and the compounds benzohydroxamic acid (BHA), 1′, anti-diphenylglyoxime (H2dpg), 2′, and dimethylglyoxime (H2dmg), 3′, as sources of NO moiety. The three complexes [RuCl2(DMSO)3(NO)]+(BA)−, 1, [RuCl2(DMSO)3(NO)]+(Hdpg)−, 2, and [RuCl2(DMSO)3(NO)]+(Hdmg)−, 3, were characterized by (FT-IR, NMR, UV-Vis) spectroscopy, thermogravimetry, and microanalysis. From FT-IR spectral data, two modes of coordination of DMSO to Ru atom through both S and O atoms were detected for 1 and 2. For 3, only S coordination was reported. Computational studies on the [RuCl2(DMSO)3(NO)]+ cationic parts, 1″, 2″ and 3″, of the investigated complexes 1, 2 and 3 were carried out by DFT. The molecular geometry and mode of attachment of Ru(II) with DMSO were performed with the B3LYP/LANL2DZ level of theory and basis set. Theoretical to the experimental agreement was achieved for analysis of IR data of the investigated complexes. Additional information about binding between the ruthenium atom and the DMSO ligand has been obtained by NBO analysis.
