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

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
