Application
三甲胺（TMA）已被用于制备聚[9,9′-双（6′-N,N,N-三甲基铵）己基）芴-co-alt-4,7-（2,1,3-苯并噻二唑） 二溴化物]（PFBT），一种用于无标记DNA微阵列的水溶性阳离子偶联聚合物。它还可用于制备苄基三甲基氯化铵，然后与乙醇钠反应以形成苄基三甲基乙醇铵。三甲基甲硅烷基化的硝酸钡-金/钛硅酸盐催化剂金表面上的TMA吸附是丙烯被氧和氢环氧化的促进剂。

We describe the synthesis of poly[9,9'-bis(6''-N,N,N-trimethylammonium)hexyl)fluorene-co-alt-4,7-(2,1,3-benzothiadiazole) dibromide] (PFBT), a cationic, water-soluble conjugated polymer used in label-free DNA microarrays. This polymer was designed to have a maximum absorbance of close to 488 nm, which meets the excitation wavelength of most commercial

Trimethylamine (TMA) and its N-oxide (TMAO) are normal components of human urine. They are present in the diet and also derived from the enterobacterial metabolism of precursors such as choline. Dietary TMA is almost entirely metabolized to and excreted as

Bacterial vaginosis is characterized microbiologically by replacement of the Lactobacillus-predominant vaginal flora by Gardnerella vaginalis, Bacteroides species, Mobiluncus species, and genital mycoplasmas. A standardized, laboratory-based diagnostic test for bacterial vaginosis is desirable in those instances in which a microscope is
