- The uralolite exhibits faint green fluorescence in shortwave ultraviolet radiation.
- Any fluorescence under ultraviolet light may also provide clues to the identity and status of a gemstone.
- A laboratory technician checked urine for ultraviolet fluorescence indicating the presence of riboflavin.
- When a beam strikes the card, the material produces fluorescence in the visible spectrum.
- Our own observations showed that fluorescence was visible throughout the cytoplasm.
- The fluorescence is not visible because the background was subtracted in each spectrum.
- This fluorescence is visible even when the paper screen is at a distance of two metres from the apparatus.
- The emitted fluorescence light from the sample surface was collected through a quartz flow cell.
- The reflected fluorescence was detected via photomultipliers.
- The greenish fluorescence seen under the light is due to an ectothrix infection of hairs, in which fungal spores form a sheath on the outside of the hair.
- This is consistent with the weak dityrosine fluorescence observed under UV light.
- The cellular genes are treated with fluorescence and literally light up the gene dots on the chip.
- Protoplasts showing bright fluorescence were counted as viable.
- My pupils contracted painfully from the relentless fluorescence of the lights above.
- This is because fluorescence at this wavelength is strongly absorbed by chlorophyll within the overlying cells.
- When illuminated with violet light, the tumour emits pink fluorescence that is detected by a highly sensitive camera.
- As pollen grains and pollen tubes emitted very strong fluorescence, the pathways of growing pollen tubes could be easily observed.
- The excited donor will emit fluorescence, leading to a decrease of efficiency.
- The fluorescence intensity emitted by the chloroplasts is dependent on the amount of light absorbed by them.
- By mixing different dyes, the colour of the fluorescence can be selected and hence a screen can be built up from loops of the fibres.
