Compound: Hydrogen tetrachloroaurate(III) trihydrate, is researched, Molecular AuCl4H7O3, CAS is 16961-25-4, about Highly efficient direct electron transfer bioanode containing glucose dehydrogenase operating in human blood. Author is Gineityte, Justina; Meskys, Rolandas; Dagys, Marius; Ratautas, Dalius.

Energy generation from bodily fluids (i. e. blood) is a significant challenge, which could be solved by designing high-performance direct electron transfer (DET) enzymic electrodes. In this paper we report a highly efficient enzymic DET bioanode based on glucose dehydrogenase, which is uniquely wired to polyaniline, gold nanoparticles and cysteamine modified gold electrode. The designed electrode demonstrates an exceptional performance by generating high chronoamperometric c.d. reaching 1 mA cm-2 at 0.1 V vs. SCE in the presence of 5 mM glucose, while in human blood samples the electrode generates average c.d. of 0.65 mA cm-2 at 0.1 V vs. SCE, which is the highest ever reported. Moreover, the electrodes demonstrate a good stability retaining 79% and 23% of the initial activity after the constant operation for 24 h in buffer solutions and blood samples, resp. The designed electrode opens new possibilities for the development of improved implantable low-power electronics.

Wang, Zexiang; Xing, Keyu; Ding, Nengshui; Wang, Suhua; Zhang, Ganggang; Lai, Weihua published an article about the compound: Hydrogen tetrachloroaurate(III) trihydrate( cas:16961-25-4,SMILESS:Cl[Au-](Cl)(Cl)Cl.[H]O[H].[H]O[H].[H]O[H].[H+] ).Category: imidazoles-derivatives. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:16961-25-4) through the article.

Herein, we propose a lateral flow immunoassay (LFIA) based on the dual spectral-overlapped fluorescence quenching of polydopamine nanospheres (PDANs) caused by the inner filter effect to sensitively detect sulfamethazine (SMZ). The fluorescence quenching LFIA device consists of four parts: absorbent pad, polyvinyl chloride pad, sample pad, and nitrocellulose membrane. Compared with traditional quenchers such as gold nanoparticles (AuNPs) with single spectral-overlapped quenching ability, PDANs can quench the excitation light and emission light of three fluorescence donors (aggregation-induced emission fluorescent microsphere, AIEFM; fluorescent microsphere, FM; and quantum dot bead, QB). The fluorescence intensity changes (ΔF) are numerically larger for PDANs-LFIA (ΔFAIEFM = 2315, ΔFFM = 979, ΔFQB = 910) than those for AuNPs-LFIA (ΔFAIEFM = 1722, ΔFFM = 833, ΔFQB =;520). AIEFM-based PDANs-LFIA exhibits a large ΔF (2315) in response to the changes in the SMZ concentration, and produces a high signal-to-noise ratio. The limit of detection (LOD) and visual LOD of LFIA based on PDANs quenching AIEFM for the detection of SMZ in chicken are 0.043 and 0.5 ng/mL, resp. The results confirm that the proposed method can be used for the detection of hazardous materials in practical applications.
