Formazan synthsis

WebZeolites and mesoporous silica can be synthesized with crystal sizes of 100 nm or less, giving these materials two dimensions on the nanoscale—the pore size and the crystal size. Nanoscale zeolites and mesoporous silica nanoparticles (MSNs) have large surface areas due to appreciable internal and external surface areas [27,28]. WebThe MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) tetrazolium assay is a popular tool in estimating the metabolic activity of living cells. The test is based on enzymatic reduction of the lightly colored tetrazolium salt to its formazan of intense purple-blue color, which can be …
