“…Uric acid and glucose were spectrofluorometrically determined by measuring the amounts of H 2 O 2 produced through each catalytic reaction by uricase and GOD for uric acid and glucose in a sample solution, respectively. The calibration curves obtained by the Uricase-Fe 3+ -TCAS [4] A-500 and the GOD-Fe 3+ -TCAS [4] A-500 methods were linear from 0.5 to 5.0 µg of uric acid in a 1.0 ml sample solution and from 0.5 to 6.0 µg of glucose in a 0.5 ml sample solution, respectively. The methods using Fe corresponding reaction by peroxidase.…”

“…In an effort to develop an artificial mimesis to solve these problems, we have investigated the enzyme-like activities of metal complexes of thiacalix [4]arenetetrasulfonate on a modified anion-exchanger (Me-TCAS [4] A-500 ). [2][3][4][5] We have shown that Fe 3+ -TCAS [4] A-500 exhibited strong peroxidase-like activity for reaction (3) and was useful as a peroxidase mimic for the spectrophotometric determination of H 2 O 2 and glucose in control sera. 2,3) Moreover, we have demonstrated that Fe 3+ -TCAS [4] A-500 exhibited strong catalytic activity for oxidation (4) The peroxidase-like activity of the Fe 3+ complex of thiacalix [4]arenetetrasulfonate on a modified anion-exchanger (Fe 3+ -TCAS [4] A-500 ) has been applied to the spectrofluorometric determination of uric acid and glucose in connection with uricase and glucoseoxidase (GOD), respectively.…”

Single bilayered organic nanotubes: anchors for production of a reusable catalyst with nickel ions

Organic nanotubes self-assembled from lipid compounds facilitate the synthesis of a new nano-catalyst with nickel ions. The nickel ions were fixed on the surface of the organic nanotubes through coordination. The nanotubes catalyzed oxidation of a wide range of organic compounds with hydrogen peroxide without organic solvent, and are reusable in at least five cycles without loss of activity.'Green chemistry' is an issue of current interest for chemical synthesis in both academia and industry. 1-4 Although many existing oxidation processes are acceptable from with regard to the products generated, production of waste and unsuccessful recovery of solvents are harmful for the environment. 5,6 Thus, the development of an environmentally friendly oxidation technology is desired. Usually, the product yields in homogenous catalytic reactions are very high because all the catalytic active sites are accessible, but the difficulty in separation of the catalyst and reaction products limits their scope. Heterogeneous catalysts appear to be a solution to this issue, 7-9 but the reactivity of these catalytic systems is generally lower than that of homogenous catalysts due to the lower availability of active sites during the catalytic reactions. Catalysts based on nanoparticles show promise as a 'bridge' between homogenous and heterogeneous catalysts, because they should combine the advantages of both. 10-14 The high surface area of these nano-catalysts dramatically enhances the contact between reactants and the catalysts, whereas their insolubility in reaction media facilitates separation from the reaction mixture. However, unsupported nanoparticles are frequently unstable, and coagulation during the reactions is often unavoidable.
