专利号:US-10150160-B2 优先权日:2014-12-04 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.

C5-nor stemmadenine compositions are also described. These compounds, for example,(+/- )-,(+)- and (-)-conolidine are potent and efficacious non-opioid analgesics in tonic and persistent pain.
专利号:US-9625466-B2 优先权日:2011-04-06 标题 :Signal amplification methods for the imaging of protein synthesis and neurotransmitter transport 发明人:BLANCHARD SCOTT C; ALTMAN ROGER B 权利人:BLANCHARD SCOTT C; ALTMAN ROGER B; UNIV CORNELL 摘要:The present invention describes the synthesis of biological samples that can be used for the purpose of enhancing the signal-to-noise ratios achievable during the imaging of protein synthesis, amino acid transport and neurotransmitter transport, particularly in applications where single-molecule resolution is demanded. The present invention provides quencher-labeled elongation factor (EF-Tu) and fluorophore-labeled tRNA. When these molecules are present in a ternary complex with GTP, the fluorescently-labeled tRNA is quantitatively quenched. Once the tRNA is incorporated into an actively translating ribosome, however, a burst of fluorescence is released and can be detected by a variety of techniques, including smFRET imaging. The invention further provides novel EF-Tu constructs for achieving quencher labeling at high levels while retaining native or near native activity in the translation reactions, as well as methods for preparing stable ternary complexes, methods of protein sequencing, methods of detecting amino acid transport using a proteoliposome assay system and the proteoliposomes systems and methods of imaging translation events in single living cells. The present invention should have an immediate impact on next-generation sequencing technologies and the detection of neurotransmitter transporter activities in both in vitro and in vivo settings, a critical component of drug activity/screening assays targeting this important class of molecules.
