Procaterol hydrochloride (Prh) can inhibit KClO3 oxidation of fluorescein isothiocyanate (FITC) to form a non-phosphorescent compound, which causes room temperature phosphorescence (RTP) of FITC in the system to enhance sharply the linear relationship between ∆Ip and the Prh content. Thus, a rapid response and highly sensitive phosphorescence sensor for the determination of Prh has been developed based on the inhibiting effect of Prh on KClO3 oxidation of FITC. This simple, high sensitivity (detection limit (LD) calculated by 3Sb /k was 0.019 fg/spot, sample volume 0.40 µl, corresponding concentration 4.8 × 10(-14) g ml(-1) ) and selective sensor with a wide linear range (0.080-11.20 g/spot) has been applied to detect Prh in blood samples, and the results were consistent with those obtained by high-performance liquid chromatography (HPLC). Simultaneously, the mechanism of the phosphorescence sensor for the detection of Prh was also investigated using infrared spectroscopy.

“…Therefore, searching for a high sensitive and accurate method for the determination of Cyt C in biological samples and discussing the relativity between the content of Cyt C and cell apoptosis have become research focus with high academic value and great significance. There have been many reports on the synthesis of multihydroxyl C 60 derivatives, F-ol derivatives, aminophenol derivatives, dendritic fullerene derivatives [13][14][15], the fluorescent property of water-soluble F-ol [16], and the determination of alkaline phosphatase [17,18], glucose [19], As (V) [20], and Mn 2+ [21] based on phosphorescent property of F-ol, showing broad prospects of F-ol in analytical application.…”

The reaction between fullerenol (F-ol) and cytochrome C (Cyt C) could be carried out to form a nonphosphorescence compound using tween-80 as photosensitizer which causes the sharp quenching of room temperature phosphorescence (RTP) of F-ol. Bearing this in mind, a novel solid substrate room temperature phosphorimetry (SSRTP) for the determination of trace Cyt C has been proposed in this study. Under the optimum conditions, the linear range of this method is 1.0 × 10 −16 -2.4 × 10 −14 g mL −1 , which is directly proportional to ΔI p of Cyt C-F-ol-tween-80 system, and the detection limit (DL) is 3.0 × 10 −17 g mL −1 . It has been applied to the determination of Cyt C in human serum and forecast of diseases, and the result matches with the enzyme-linked fluorescence immunoassay (ELISA). Meanwhile, the reaction mechanism of SSRTP for the determination of Cyt C and the enhancing effect of tween-80 on RTP of F-ol were also discussed.
