Web28 aug. 2024 · Cold vapor atomic fluorescence spectroscopy (CVAFS) uses the same technique as AFS, but the preparation of the sample is adapted specifically to quantify the presence of heavy metals that are volatile, such as mercury, and allows for these elements to be measured at room temperature. Figure 1.11. 1 The basic setup for CVAFS. WebAbstract. A novel DNA aptamer beacon is described for quantification of a 26-amino acid C-telopeptide (CTx) of human type I bone collagen. One aptamer sequence and its reverse complement dominated the aptamer pool (31.6% of sequenced clones). Secondary structures of these aptamers were examined for potential binding pockets.

WebFluorescence intensity in microplate readers is detected with photomultiplier tubes (PMTs). They multiply the signal using the photoelectric effect and convert the light into an electric signal. For fluorescence intensity measurements in microplate readers, two different PMTs are used, which differ in their sensitive wavelength range.
