Photocatalytical reduction of disulphide bonds in peptides on Ag-loaded nano-TiO2 for subsequent derivatization and determination.
نویسندگان
چکیده
We reported an alternative strategy to reduce disulphide bonds in peptides with Ag-nanoparticle loaded nano-TiO(2) (Ag/TiO(2)) under UV irradiation. The feasibility of this strategy was adequately demonstrated using the model peptides oxidized glutathione, vasopressin and insulin, which contain various disulphide bonds, as well as by its application to the determination of Cd-induced phytochelatins in Phaeodactylum tricornutum.

متن کاملEffect of Formation of Ag2Ti4O9 Phase on Photocatalytic Activity of Ag-TiO2 Nanocomposite
Ag-TiO2 nanocomposite with the optimum concentration of 1wt% was produced by a sol-gel process using Rhodamine B for the catalytic activity. The initial samples were prepared by heat treatment at various temperatures (266, 338, 390, 485, 600 and 700°C) with a holding time of 2 h. DTA and XRD of these samples led to choosing the temperature of 530°C as the heat treatment temperature. Then some s...
