AB  - Metal acetate complexes are highly interesting in designing and synthesizing metal–organic frameworks, which have potential applications in gas storage, molecular sieves, ion exchange, and catalysis. Cadmium is well recognized as an industrial pollutant and a food contaminant that severely affects human health. For these reasons, the detection and analysis of Cd are of great interest. A major challenge in studying cadmium compounds' structure is that Cd2+ can have a wide range of coordination numbers and diverse geometries. (MA)LDI is extremely useful for detecting Cd(OAc)2·2H2O and investigating Cd's complex and flexible nature. We applied LDI to detect and characterize the Cd-related clusters and MALDI approach to investigate the Cd(OAc)2x2H2O reactivity and detectability with the five different organic matrices. The results revealed that in the solid-state Cd(OAc)2x2H2O tend to form coordination polymers, and in the presence of coordinating ligands (matrix molecules) form smaller complexes. In addition, the correlation between Cd-related LOD and matrix features was observed and discussed, indicating that the LODs of this analyte strongly depend on the optical absorption of the matrix-analyte adduct.

AB  - A binary system composed of carbon dots (CDs) and N-doped CDs (N-CDs) embedded in an organic matrix was used for the analysis of cholesterol by MALDI (matrix-assisted laser desorption and ionization time-of-flight) mass spectrometry, as a model for detection of small, biologically relevant molecules. The results showed that both CDs are sensitive to the cholesterol and can be used either alone or in a binary system with 2,5-dihydroxybenzoic acid (DHB) to enhance the detection process. It was found that both COOH and NH2 groups on CDs surface contributed to the enhancement in the cholesterol detection by MALDI mass spectrometry in the presence of inorganic cations. Nevertheless, in the presence of NaCl, N-CDs led to a better reproducibility of results. It was due to the coexistence of positive and negative charge on N-CDs surface that led to a homogeneous analyte/substrate distribution, which is an important detection parameter. The enhancing effect of carbon dots was linked to a negative Gibbs energy of the complex formation between CDs, Na+, cholesterol and DHB, and it was supported by theoretical calculations. Moreover, upon the addition of CDs/N-CDs, such features as a low ionization potential, vertical excitation, dipole moment and oscillator strength positively affected the cholesterol detection by MALDI in the presence of Na+. © 2021 Elsevier Inc.
