A new electrochemical biosensor based on the human serum albumin/graphene oxide/3-aminopropyltriethoxysilane modified indium tin oxide electrode (ITO/APTES/GO/HSA) has been developed for the discrimination of tryptophan (Trp) enantiomers. The electrode has been characterized by scanning electron microscopy (SEM) and electrochemical techniques. The electrochemical behaviors of the enantiomeric pairs (d- and l-Trp) at the ITO/APTES/GO/HSA electrode have been investigated by cyclic voltammetry in the concentration range of 0.10-1.0. mM. A clear separation between the oxidation peak potentials of d- and l-Trp, at 0.86 and 1.26. V, respectively, has suggested that the ITO/APTES/GO/HSA electrode can be used as an electrochemical biosensor for the discrimination of Trp enantiomers. In order to find the percentage of an enantiomeric form of tryptophan in a mixture, the ITO/APTES/GO/HSA electrode is used for the simultaneous detection of d- and l-Trp which showed that the percentage of one enantiomeric form can be easily measured in the presence of the other. © 2012 Elsevier B.V.

In situ deposition of catalysts are drawing attention to the liquid/liquid interfaces by using raw materials for the energy conversion reactions such as hydrogen evolution and oxygen reduction. Herein, in situ generation of amorphous molybdenum sulfide on reduced graphene oxide (rGO/MoSx) is investigated in the hydrogen evolution reaction (HER) by decamethylferrocene electron donor at the liquid/liquid interfaces by using (NH4)2MoS4 and graphene oxide precursors in the aqueous phase. rGO/MoSx catalyst shows better catalytic activity than the uncatalyzed reaction and free-MoSx, which increase the HER rate 57- and 1.7-fold, respectively. The enhanced catalytic activity of rGO/MoSx catalyst is related to the increased surface area, active sites and conductivity of rGO. The catalytic activity of rGO/MoSx are examined by four-electrode voltammetry and also two-phase reactions. The obtained rGO/MoSx catalyst are characterized in detail by structural and morphological techniques.
