“…In the mentioned period, several reviews have been published describing different applications of CE to analyze specific groups of compounds with potential interest in food analysis and/or Foodomics 3. Table 1 shows a summary of these review papers 4–26. As can be seen, CE has been applied to analyze contaminants 5, 10, 13, 16–18, 24, chiral compounds 11, 15, polyphenols 8, 9, 12, 25, amino acids 14, nucleosides and nucleotides 19 in different foods.…”

The analysis of food components using capillary electromigration methods is reviewed in this work. Papers that were published from February 2009 to February 2011 are included following the previous review by Herrero et al. (Electrophoresis, 2010, 31, 205-228). The analysis of amino acids, biogenic amines, peptides, proteins, DNAs, carbohydrates, phenols, polyphenols, pigments, toxins, pesticides, vitamins, additives, small organic and inorganic ions and other compounds found in foods and beverages are reviewed, as well as those applications of CE for monitoring food interactions and food processing. The use of microchips, CE-MS and chiral-CE in food analysis is also discussed as well as other current and foreseen trends in this area of research including new developments in Foodomics.

“…Other detection schemes, such as contact or contacless capacitively coupled conductivity detection, electrochemical, (electro)chemiluminescence, infrared spectroscopy, and NMR, are less suitable and much less utilized to peptide detection in CE and CEC than UV absorption, fluorescence, and MS detectors. For that reason, only some recent reviews are cited here, which are dealing with general developments and applications of these detectors, such as electrochemical , conductivity , chemiluminescence , electrochemiluminescence , mid‐infrared , and NMR , where few applications of these detectors for CE separation of peptides as model analytes could be mentioned.…”

The review presents a comprehensive survey of recent developments and applications of capillary and microchip electroseparation methods (zone electrophoresis, ITP, IEF, affinity electrophoresis, EKC, and electrochromatography) for analysis, isolation, purification, and physicochemical and biochemical characterization of peptides. Advances in the investigation of electromigration properties of peptides, in the methodology of their analysis, including sample preseparation, preconcentration and derivatization, adsorption suppression and EOF control, as well as in detection of peptides, are presented. New developments in particular CE and CEC modes are reported and several types of their applications to peptide analysis are described: conventional qualitative and quantitative analysis, determination in complex (bio)matrices, monitoring of chemical and enzymatical reactions and physical changes, amino acid, sequence and chiral analysis, and peptide mapping of proteins. Some micropreparative peptide separations are shown and capabilities of CE and CEC techniques to provide relevant physicochemical characteristics of peptides are demonstrated.

“…Chemiluminescence (CL) has been widely applied to clinical chemistry, bioanalysis and environmental analysis due to its numerous advantages such as high sensitivity, wide range of linearity and the need for simple instrumentation . The luminol CL reaction was first reported in 1928, since then several types of catalysts for CL reactions have been developed, including metal ions, enzyme, and so on .…”

Improvement of mimetic peroxidase activity of gold nanoclusters on the luminol chemiluminescence reaction by surface modification with ethanediamine

Peroxidase is a commonly used catalyst in luminol-H O chemiluminescence (CL) reactions. Natural peroxidase has a sophisticated separation process, short shelf life and unstable activity, therefore it is important to develop peroxidases that have both high catalytic activity and good stability as alternatives to the natural enzyme. Gold nanoclusters (Au NCs) are an alternative peroxidase with catalytic activity in the luminol-H O CL reaction. In the present study, ethanediamine was modified on the surface of Au NCs forming cationic Au NCs. The zeta potential of the cationic Au NCs maintained its positive charge when the pH of the solution was between 4 and 9. The cationic Au NCs showed higher catalytic activity in the luminol-H O CL reaction than did unmodified Au NCs. A mechanism study showed that the better performance of cationic Au NCs may be attributed to the generation of O on the surface of cationic Au NCs and a positive surface charge, for better affinity to luminol. Cationic Au NC, acting as a peroxidase mimic, has much better stability than horseradish peroxidase over a wide range of temperatures. We believe that cationic Au NCs may be useful as an artificial peroxidase for a wide range of potential applications in CL and bioanalysis.
