Calibration of the linear response range of x-ray imaging plates and their reader based on image grayscale values

A simple, rapid, and specific method for Hg(II) detection has been proposed based on the fluorescence change ofN-acetyl-L-cysteine-capped CdTe quantum dots (QDs). The presence of Hg(II) ions could quench the fluorescence of QDs at 565 nm and meanwhile produce new peak in 700–860 nm wavelength range. The linear response range is 20–430 nM with the detection limit at 8.0 nM Hg(II). It was found that the position of the new peak was irrelevant to the size of QDs. Furthermore, the mechanism of the quenching of QDs fluorescence by Hg(II) and the appearance of new peak in near-infrared area were also discussed and deduced through ultraviolet absorption spectrum, fluorescence spectrum, and X-ray photoelectron spectrum.

Ssat Activity

Acetyl amantadine (AcAm) is produced from amantadine (Am) in vivo upon catalysis by spermidine/spermine N1-acetyl transferase (SSAT). SSAT is a biomarker for multiple aggressive cancers, and the analysis of AcAm in urine has been promoted as a proxy measure for the early detection of cancer. We report here the development and optimization of cucurbit[7]uril–dye pair based indicator displacement assay (IDA) for the detection of AcAm in solution. In deionized water, using Rhodamine B as the dye, the limit of detection of AcAm was 0.087 μM with a linear response range from 0 to 1 μM. Using berberine as the dye, the limit of detection was 0.077 μM with the same range of linear response. Our efforts and difficulties in translating this assay to function in human urine are also described. We achieve a partial response of the berberine IDA to the presence of AcAm in urine that has undergone a simple PD-10 desalting step.
