The presence of Cronobacter sakazakii must be controlled in infant powder plants, because it may cause infectious disease infants, with high mortality. Testing for C. powdered formula should performed before delivery, and requires rapid specific detection methods. In this study, we established a surface-enhanced Raman scattering (SERS) immunochromatographic test strip the quantitative determina...

P-aminothiophenol (PATP) is a well-known molecule for the preparation of self-assembled monolayers on gold via its thiol functional group. After adsorption, it has been demonstrated that this molecule is anchored to gold through its thiol group, and standing nearly upright at the surface with the amino functional group on top. This molecule has been extensively studied by surface enhanced Raman...

2-aminothiophenol and 4-methoxybenzaldehyde were cyclized under microwave irridation and solvent free conditions to synthesize 2-(4-methoxyphenyl)benzo[d]thiazole. The molecular structure and vibrational frequencies of the title compound in the ground state have been investigated with ab initio (HF) and density functional theory methods (BLYP, B3LYP, B3PW91 and mPW1PW91) implementing the standa...

When p-aminothiophenol (PATP) is used as a probe molecule and adsorbs on silver and gold nanogaps, a significant change of relative SERS intensities can be observed. Our DFT calculations show that surface photocatalytic coupling reactions yield a new surface species of p,p'-dimercaptoazobenzene (DMAB) causing the significant change in the SERS spectra.

A series of new dicarboxylic acid derivatives of 1,3,4-thiadiazines, 1,4-benzopiperizines, 1,4-thiazines, 1,3-thiazoles, 1,3-oxazoles and 1,3-imidazoles have been synthesized in 80-87% yield by the environmentally benign microwave induced technique involving the cyclocondensation of 2,3-dibromosuccinic acid with 2-aminothiophenol, o-phenylene diamine, 1,2,4-triazole, amidinothiocarbamide, amidi...

Periodic density functional theory calculations were performed to address the geometric and electronic structure of a Pd/4-aminothiophenol/Au(111) metal-molecule-metal contact. In a systematic approach, we first determined the adsorption of single 4-aminothiophenol (4-ATP) molecules on Au(111). Like other aromatic molecules, 4-ATP molecules adsorb preferentially at near-bridge sites in a tilted...

Synthesis Reaction of 1a,b with 2-aminothiophenol and sodium ethanolate in ethanol does not give the expected tetracyclic ring systems, but surprisingly the spirocompounds 2 are obtained. A [2+4] cycloaddition of the intermediately formed 1,2-benzoquinone-2-imine-1-thione with the aurone was postulated. Under these conditions the thioaurones 1c,d showed no reaction. After reaction of 1with 2-am...
