“…[1,2] The distinction of saccharides is the main technical challenge for the food industry when dealing with the public health problem of adding saccharides to foods. [3][4][5] Although the 'macro' sequence of the sugar chain and the 'micro' conformation of the sugar ring are variable, in most cases the hydroxyl group is the unique functional group of saccharides, and molecular recognition of carbohydrates has become particularly difficult. [6] We can only start to discriminate the saccharides by analyzing the number of hydroxyl groups and the spatial conformation of a certain hydroxyl group.…”

A colorimetric sensor array based on natural pigments was developed to discriminate between various saccharides. Anthocyanins, pH‐sensitive natural pigments, were extracted from fruits and flowers and used as components of the sensor array. Variation in pH, due to the reaction between saccharides and boronic acids, caused obvious colour changes in the natural pigments. Only by observing the difference map with the naked eye could 11 common saccharides be divided into independent individuals. In conjunction with pattern recognition, the sensor array clearly differentiated between sugar and sugar alcohol with highly accuracy and allowed rapid quantification of different concentrations of maltitol and fructose. This sensor array for saccharides is expected to become a promising alternative tool for food monitoring. The link between anthocyanin and saccharide detection opened a new guiding direction for the application of anthocyanins in foods.

“…Direct electron transfer over a longer working distance can be accomplished through the sulfonated conjugate polyelectrolyte, which has a strong signal in DNA detection (12). And a probe system as fluorescence turn-on assay of simple saccharides is based on three anionic conjugated polyelectrolytes and three quenched molecules substituted by boric acid (13). However, almost all the anionic CPEs are consisted of phenyl units (14), thiophene derivatives (15) and fluorene monomers (16), and there are few literatures focused on water soluble N-heterocyclic systems.…”

AbstractTwo benzimidazole-based conjugated polyelectrolytes (+)-PPBIPV and (-)-PPBIPV which have opposite charges on their side chains were synthesized via Heck coupling reaction and characterized by 1H-NMR, UV-vis and PL spectroscopy. These two polyelectrolytes are both consisted of benzimidazole derivatives and phenylenevinylene units. The absorption and emission spectra reveal that the polymers both have solvent-dependency and concentration-dependency, and they exhibit aggregation effect in aqueous solution. In the respect of ion detection, the aqueous solution of (+)-PPBIPV has excellent selectivity and sensitivity for Fe3+. Moreover, Pd2+ can almost completely quench the fluorescence of (+)-PPBIPV in methanol solution, and its quenching constant KSV is 5.93×104 M-1. For (-)-PPBIPV, Sn2+ can double the fluorescence intensity of its aqueous solution, while (-)-PPBIPV has good identification for Fe3+ in methanol with a KSV = 3.44×105 M-1. Hence, two polyelectrolytes have considerable potential to become effective fluorescent sensing materials for some specific metal ions. All of the stoichiometric relationships between metal ions and conjugated polyelectrolytes were calculated using Benesi-Hildebrand equation.

Array-based Generation of Response Patterns with Common Fluorescent Dyes for Identification of Proteins and Cells

A differential array consisting of commercially available common fluorescent dyes was constructed for the identification of proteins and human cancer cells. Fluorescence of dyes was differently altered by mixing with proteins and human cancer cells, generating response patterns that are unique to the analytes. Linear discriminant analysis of the obtained patterns enabled the accurate identification of eight proteins and three human cancer cells. As this system can be easily prepared, it would offer a unique opportunity for array-based differential biosensing.
