标题 :Universal one-pot and up-scalable synthesis of SERS encoded nanoparticles
发明人：PAZOS PÉREZ NICOLÃ?S; MIR DE SIMÓN BERNAT
权利人:MEDCOM ADVANCE S A; MEDCOM ADVANCE S A
摘要:The universal one-pot and up-scalable synthesis of SERS encoded nanoparticles relies on the controlled co-absorption of mercaptoundecanoic acid (MUA) and the Raman code on the metallic surfaces of the nanoparticles. In contrast to most of the reported procedures which typically involve complex steps, the present method has demonstrated to be an easy and fast one-pot approach for the production of SERS-encoded nanoparticles. This versatile strategy allows for the SERS codification of particles with every molecule with affinity toward the metal surface, independently of its chemical nature, as exemplified here in the fabrication of 31 different encoded particles using the same standard procedure. In addition to the easiness of preparation, scalability to the liter regime, stability in aqueous solutions including PBS and chemical diversity, our SERS-encoded particles show considerably higher optical efficiency than those fabricated by using PEG or PVP polymers.

摘要:A new process for the preparation and purification of 4-4′-diamino-diphenyl-sulfone (dapsone) is described. The process described is a three step process comprising a condensation reaction with the synthesis of a thioether intermediate and then steps of oxidation and reduction in suitable conditions in order to obtain a product with good yield and purity.

摘要:An economic, direct synthetic method for producing water soluble ZnS QDs that are ready for bioconjugation is provided. The method can produce aqueous ZnS QDs with emission wavelengths varying from 400 nm to 700 nm. Highly luminescent metal sulfide (MS) QDs are produced via an aqueous synthesis route. MS QDs are capped with thiol-containing charged molecules in a single step. The resultant MS QDs exhibit the distinctive excitonic photoluminescence desired of QDs and can be fabricated to avoid undesirable broadband emissions at higher wavelengths. The aqueous ZnS QDs are stable in biological fluids over a long period of time. In addition, non-toxic ZnS QDs have been produced with good photoluminescence properties.

标题:Convergent synthesis of proteins by kinetically controlled ligation

权利人:UNIV CHICAGO
摘要:The present invention concerns methods and compositions for synthesizing a polypeptide using kinetically controlled reactions involving fragments of the polypeptide for a fully convergent process. In more specific embodiments, a ligation involves reacting a first peptide having a protected cysteyl group at its N-terminal and a phenylthioester at its C-terminal with a second peptide having a cysteine residue at its N-termini and a thioester at its C-termini to form a ligation product. Subsequent reactions may involve deprotecting the cysteyl group of the resulting ligation product and/or converting the thioester into a thiophenylester.
