UV\u2010visible spectroscopy, Fourier transform infrared (FT\u2010IR) spectroscopy, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were applied for the characterization of functionalized CdS NPs. The synthesized CdS\u2010ATP and CdS\u2010MUA NPs exhibit uniform size distribution with diameter of 15\u201325\u2009nm and 20\u201330\u2009nm, respectively. The \u2010NH\n                    <jats:sub>2<\/jats:sub>\n                    (ATP) and \uf8ffCOOH (MUA) groups modified on the surfaces of CdS NPs provide ionizable moieties for efficient transfer of protons during the desorption\/ionization of analytes. The functionalized CdS NPs have desirable properties for the analysis of peptides in reflectron MALDI\u2010TOF\u2010MS with suppressed background noise and increased mass resolution (4\u201313\u2010fold) in linear MALDI\u2010TOF\u2010MS. The application of CdS\u2010MUA NPs and SA as the co\u2010matrices in MALDI\u2010MS is demonstrated for the analysis of hydrophobic proteins from soybean.
