发明人：LI YALI; ZHU HUAXING; ZHANG QINGYI
权利人:NOVOPROTEIN SCIENT INC
摘要:Provided is a method for enzymatic synthesis of capped mRNA in one tube. In the method, the step of purifying mRNA after IVT is omitted, and a capped product having a higher capping efficiency and fewer by-products is obtained. The method provided for enzymatic synthesis of capped mRNA is simple, convenient and short in terms of the process, and is rapid and efficient, so that the production process of a capped mRNA product is simplified, and a production cost is reduced, which is conducive to industrial production.

标题 :Universal one-pot and up-scalable synthesis of SERS encoded nanoparticles

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.

标题 :Method for the synthesis of metal nanoparticles in aqueous environment without the use of shape directing agents
发明人：MOGLIANETTI MAURO; POMPA PIER PAOLO
权利人:FONDAZIONE ST ITALIANO TECNOLOGIA
摘要:The present disclosure relates to a seed-growth based method for the synthesis of metal nanoparticles of controlled shape (cubes, cuboids, octahedrons) and size in an aqueous environment, without the use of shape directing agents. The method involves a first step of preparing a solution comprising water, metal seed growth nanoparticles, a metal salt comprising the same metal as the metal seed growth nanoparticles, and a reducing agent; and a second step of heating the solution to between 9 and 130° C. at a rate of between 1° C./min and 5° C./min and at a pressure of between 1 and 5 atm. The method may also be carried out in a reduced oxygen atmosphere and the concentration of oxygen disclosed in the solution may be less than the concentration of oxygen in an oxygen saturated solution.
