Multispectral technique combines with fluorescing agent for targeted cancer surgery
… that are detectable using current visual and tactile detection techniques. The current imaging agent uses a green fluorescent dye with a relatively short wavelength that limits its ability to pass through the body, with the result that it cannot …

Vision-based analyzer fingerprints disease
… the image field. To solve this problem, ABI adds a fluorescent dye to every spot along with the oligonucleides. When excited by a flash of light from an array of LEDs, the fluorescent dye responds by emitting light at 658 nm. “Most fluorescent …

Carl Zeiss integrates Colibri white LED illumination into fluorescence microscopy systems
… already mentioned the dangers of overexposure to light: phototoxicity of the specimen, and photobleaching of the fluorescent dye or protein. Overexposure can be avoided by attenuating the light intensity and by limiting the duration of the illumination …
