• by 7%. The reduced surface coverage facilitated desorption of the surface molecules and bridging of the metal cores at reduced temperatures [99]. Some ligands, for example 2-mercaptoethanol or thioglycolic acid, have been reported to cause chain-like agglomeration of gold nanoparticles during their

In a similar study, the exchange of citrate ligands by thioglycolic acid (Figure 2) allowed the authors to reduce the surface charge density, manipulate Coulomb repulsion between the particles, and initiate agglomeration in solution. Appropriate particle charges

• . Finally, Cd(OOCCH3)2·2H2O (0.2 M) and 4 mL of thioglycolic acid (0.2 M) was added into 40 mL of above solution under vigorous stirring. Subsequently, this homogenous suspension was transferred to 50 mL teflon-lined stainless steel autoclave and kept at 140 °C for 48 h. After the completion of reaction

• used bare or primed, prior to the coating with LPSQ-COOH/X, with a monolayer of N-acetylcysteine, citric acid or thioglycolic acid. The primers are bound to mica by ionic bonds (carboxylates) and simultaneously provide the substrate with new organic functions capable of hydrogen bonding [49]. Atomic

• silsesquioxanes (LPSQ-COOH/X) were prepared (Scheme 1, Table 1) by the two-step addition of organic thio-derivatives, i.e., thioglycolic acid, N-acetylcysteine (NAC), glutathione (GSH) and cysteine hydrochloride (Cys-HCl), to the side chains of vinyl-containing LPSQ precursors obtained by polycondensation of

• small molecules [49]. They should be simultaneously capable of the formation of surface salts and hydrogen bonds with functional groups in side chains of LPSQ-COOH/X. Consequently, thioglycolic acid (TG), citric acid (CA) and N-acetylcysteine (NAC) were selected and used as primers to modify the surface
