30 de ago. de 2021 · We describe here how the conversion of the ortho-carboxy moiety of a given rhodamine into substituted acyl benzenesulfonamides and alkylamides permits the systematic tuning of the equilibrium of spirocyclization with unprecedented accuracy and over a large range.
En este artículo se presenta el diseño y desarrollo de un microscopio de epifluorescencia de bajo costo basado en una fuente laser de excitación, un filtro barrera simplificado, y un sistema embebido (hardware y software) para la visualización y el control digital.
17 de dic. de 2021 · Replacing the benzene ring in the rhodamine core with a permanently charged 1,3-disubstituted imidazolium markedly improves the photoswitching behavior and overall performance of (direct) stochastic optical reconstruction microscopy ( (d)STORM).
23 de dic. de 2009 · Fluorescent markers emitting in the red are extremely valuable in biological microscopy since they minimize cellular autofluorescence and increase flexibility in multicolor experiments. Novel rhodamine dyes excitable with 630 nm laser light and emitting at around 660 nm have been developed.
15 de sept. de 2021 · We describe here how the conversion of the ortho-carboxy moiety of a given rhodamine into substituted acyl benzenesulfonamides and alkylamides permits the systematic tuning of the equilibrium of spirocyclization with unprecedented accuracy and over a large range.
Rhodamine 123 is a cell-permeant, cationic, green-fluorescent dye that is readily sequestered by active mitochondria without cytotoxic effects. This product has been used to assay mitochondrial membrane potential in populations of apoptotic c.
9 de abr. de 2010 · Marker molecules: The newly synthesized fluorinated rhodamines are cell-permeable and perform excellently in optical microscopy applications, such as single-molecule detection and stimulated emission depletion (STED) nanoscopy (see picture). Abstract.
