    • ‘Protoplasts that fluoresced brightly and exhibited normal morphology were considered to be viable.’
    • ‘Several bodily fluids fluoresce under laser or UV light; however, it is usually necessary to develop latent fingerprints using fluorescent powders or sprays to enhance the details of the print.’
    • ‘At cystoscopy, only limited tumor fluorescence was observed, but the resected specimens fluoresced brightly, indicating absorption of the short wavelength portion of the cystoscopic light source.’
    • ‘One molecule will be caused to fluoresce by the first laser and not the rest or maybe the second and not the first and third and so on.’
    • ‘If the system works as scientists hope it will, plants will be genetically induced to fluoresce, or glow, green, when they detect minute quantities of anthrax or some lethal chemical agent in the air.’

    • ‘A transverse section of a leaf shows that the sclerenchyma bands are constituted of narrow fibres with thick walls that fluoresce brightly at 450 nm.’
    • ‘This allows progeny to be genotyped as pupae, since the guts of pupae carrying a green balancer fluoresce brightly.’
