“…In a similar fashion already reported in literature for the synthesis of GSH-and NAC-CS and GC polymer conjugates [9], [10], [16], GSH-and NAC-GC thiomers were obtained by the formation of amide bonds between primary amino groups linked to the C-2 of pyranose ring of GC backbone and glycine carboxylic acid groups or cysteine carboxylic acid groups of GSH and NAC, respectively. Thiol groups of polymers, and other thiols in the proteins, can be oxidized to disulfides in aqueous solutions by intra-and/or intermolecular reactions [23], [24]. The pH affected the oxidation lability of thiol groups.…”

“…Even molecular oxygen will oxidize thiols in the presence of trace amounts of metal ions [98]. The nature of neighbouring groups greatly influences the oxidation of thiols [99]. The side chains of His, Tyr, Met, Cys and Trp residues can be oxidized via photo-oxidation in the presence of dyes [96].…”

Now that enzymes are available that are stable above 100 mC it is possible to investigate conformational stability at this temperature, and also the effect of high-temperature degradative reactions in functioning enzymes and the inter-relationship between degradation and denaturation. The conformational stability of proteins depends upon stabilizing forces arising from a large number of weak interactions, which are opposed by an almost equally large destabilizing force due mostly to conformational entropy. The difference between these, the net free energy of stabilization, is relatively small, equivalent to a few interactions. The enhanced stability of very stable proteins can be achieved by an additional stabilizing force which is again equivalent to only a few stabilizing interactions. There is currently no strong evidence that any particular interaction (e.g. hydrogen bonds, hydrophobic interactions) plays a more important role in

“…Oxidation of thiol groups to the disulfide was, for example, investigated by Barron et al 37) and by Overberger and Ferraro. 38) They demonstrated that the oxidizability of dithiols increases as the distance between the thiol groups decreases. Negishi and Tsukuda synthesized gold clusters using the oxidation of a dithiol: meso-2,3-dimercaptosuccinic acid.…”

Gold nanoparticles grow area-selectively on focused-ion-beam-irradiated areas of a silicon substrate in response to exposure to a pure chloroauric acid solution. Thus, this area-selective metal deposition does not use resist films, silane-coupling agents, and electrolysis. Hydrofluoric acid, almost always used in electroless deposition of gold on silicon, is also unnecessary as long as micro/nanoscopic areas are targeted. This review highlights how we developed the method for the growth of gold on a desired local region of silicon products, including commercially available atomic force microscopy probes as well as silicon wafers, and discusses the mechanism.
