(1) A laboratory technician checked urine for ultraviolet fluorescence indicating the presence of riboflavin.(2) It seemed that the uranium compounds emitted yet another kind of radiation, not X-rays and not related to fluorescence .(3) 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.(4) Steady-state fluorescence parameters were measured at each light level.(5) As pollen grains and pollen tubes emitted very strong fluorescence , the pathways of growing pollen tubes could be easily observed.(6) At each step of the dynamics, the instantaneous fluorescence lifetime was computed.(7) My pupils contracted painfully from the relentless fluorescence of the lights above.(8) The emitted fluorescence light from the sample surface was collected through a quartz flow cell.(9) Any fluorescence under ultraviolet light may also provide clues to the identity and status of a gemstone.(10) Leaves were kept in darkness for 30 min before recording the fluorescence parameters.(11) To do so, it is common to gain a measure of PSII electron transport using chlorophyll fluorescence .(12) This is consistent with the weak dityrosine fluorescence observed under UV light.(13) There are many familiar examples of fluorescence and phosphorescence in our daily lives.(14) The content of the fluorescence was determined using quinine fluorescence as a standard.(15) The cellular genes are treated with fluorescence and literally light up the gene dots on the chip.(16) One of the main attractions of chlorophyll fluorescence is that it appears to give a measure of photosynthesis.
