Recommanded Product: 16961-25-4. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Hydrogen tetrachloroaurate(III) trihydrate, is researched, Molecular AuCl4H7O3, CAS is 16961-25-4, about Graphite/gold nanoparticles electrode for direct protein attachment: characterization and gas sensing application.
In this work, graphite/gold nanoparticles (G/AuNPs) were synthesized through a facile chem. method, and its potential application for direct protein attachment for electrochem. detection of carbon monoxide (CO) was investigated. The preparation of G/AuNPs electrodes was optimized by synthesizing the nanoparticles in different concentration of HAuCl4ยท3H2O at various temperatures The G/AuNPs electrode was subsequently modified by four types of mercaptopropionic acid, including 1-mercaptopropionic, 3-mercaptopropionic, 6-mercaptopropionic, and 11-mercaptopropionic acid, to achieve the best structure for protein attachment. Visible absorption and electrochem. studies showed that 3-mercaptopropionic acid possesses the best performance regarding the elec. conductivity between electrode and protein redox center. The cyclic voltammetry results revealed that the modified electrode has an appropriate performance for CO detection at very low concentrations while keeping a linear response. The limit of detection for the modified electrode was calculated to be about 0.2 ppb. Finally, the interactions of cytochrome C and carbon monoxides were simulated using mol. dynamics (MD), and the effect of protein conformation changes on the electrochem. signal was thoroughly examined The simulation results suggested that the proposed electrochem. sensor has an acceptable performance for the detection of CO due to less fluctuation of amino acids near the protein chain in the presence of CO mols.
