Recent Examples on the Web Using super-resolution fluorescence and electron microscopes, the researchers observed a detailed sequence of events involving a stiff shaft and a flexible, whiplike filament that starts out coiled around it within the nematocyst. 
Viviane Callier, Scientific American, 18 Aug. 2022 Specifically, there was an inhibition of fluorescence with the Parkinson’s disease patient samples. William A. Haseltine, Forbes, 17 Aug. 2022 Essentially, if his X-ray fluorescence (XRF) analyzer identified Bromine in a white flower, Van Gogh had initially intended it to be pink. Maggie Menderski, The Courier-Journal, 23 June 2022 Their video has documented fluorescence in some of the coral, an unusual response in offshore waters that Foord said could be protecting them from solar rays. Curt Anderson And Cody Jackson, Sun Sentinel, 9 May 2022 No halogen, no fluorescence, and no colored light, unless used sparingly and very, very chicly. Tom Rasmussen, Vogue, 18 May 2022 Several types of quantum dots were tested on the silkworms for safety and fluorescence. Elizabeth Gamillo, Smithsonian Magazine, 8 Mar. 2022 The company is using ultra-high throughput fluorescence microscopy to measure individual base pairs, across billions of fragments of DNA placed in nanowells built into glass wafers. Tom Coughlin, Forbes, 28 Oct. 2021 The chips fluoresce, and this fluorescence can be intensified or dimmed by nearby magnetic substances such as the cuticulosomes.
