An ultrasensitive photoelectrochem. (PEC) aptasensor based on Bi4Ti3O12/Pd@Au/Ag2S was proposed for the detection of Hg2+. The indium tin oxide (ITO) electrode was first decorated with the nested hollow bismuth titanate (Bi4Ti3O12) that functioned with Pd@Au as an electron mediator to accelerate the photocurrent conversion, and then silver sulfide (Ag2S) nanoparticles were grown in-situ to enhance the PEC response. The band gap of Ag2S is so narrow that photogenerated electrons are easily generated under illumination. Pd@Au acts as an electron medium to facilitate electron transfer from the conduction band of Ag2S to the valence band of Bi4Ti3O12. The quant. detection of Hg2+ was achieved based on the thymidine-Hg2+-thymidine (T-Hg2+-T) specific interaction. The results showed that the PEC aptasensor showed a wide linear range (1 mM-0.1 pM) and a low detection limit (19 fM). In addition, the aptasensor has excellent selectivity, reproducibility and stability, providing a feasible method for the detection of Hg2+. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Electric Literature of Cl4Na2Pd).
Sodium tetrachloropalladate(II) (cas: 13820-53-6) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Electric Literature of Cl4Na2Pd
