Investigation of silver binding to polyamidoamine (PAMAM) dendrimers by ESI tandem mass spectrometry.
Electrospray ionization tandem mass spectrometry (ESI-MS/MS) was used to probe the binding of silver ions and reduced silver species with polyamidoamine generation 1 amine-terminated (PAMAMG1NH2) and generation 2 hydroxyl-terminated (PAMAMG2OH) dendrimers. At Ag(+)/PAMAMG2OH molar ratios of 1, 2:1 and low abundance 3:1 complexes emerge. Similar...
متن کاملSynthesis of G0 aminopolyol and aminosugar dendrimers, controlled by NMR and MALDI TOF mass spectrometry
Organic compounds designed to serve as stable dendrimer cores were developed. A series of aminosugar and amino polyol containing G0 dendrimers were synthesized. The reaction mixture composition was checked by MALDI TOF mass spectrometry, while that of purified products - by 1H and 13C NMR combined with 2D NMR spectroscopy as well as MALDI TOF MSMS mass spectra. Mass spectrometric fragmentation ...

متن کاملMALDI mass spectrometry imaging in oncology (Review).
Matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI) has improved over the years and is increasingly being used for biomarker discovery directly from human tissue sections. State-of-the-art technology currently enables a resolution down to 20 µm. MSI therefore allows the correlation of spatial and temporal protein expression profiles with distinct morphological fe...
