Abstract
A novel ratiometric fluorescent probe has been developed through a simple synthetic route for the detection of alkaline phosphatase(ALP) in aqueous media and for fluorescence imaging in living cells. The introduction of a spontaneous-degradation spacer in the design of the fluorescent probe is beneficial for the ratio detection method and allows the selection of a fluorophore with an amino group. Under catalysis by ALP, the phosphate monoester bond breaks; this is followed by 1,4-elimination, decomposition of the carbamate moiety, and subsequent formation of the 4-amine-1,8-naphthalimide fluorophore. The probe APN shows a significant fluorescence colour change from blue to green in response to ALP, and the fluorescence intensity ratio of the probe solution (F550/F480) has a good linear relationship with the ALP concentration in the range of 0 to 100 U L-1. Our studies have demonstrated that APN exhibits high accuracy in recognising ALP, with a detection limit as low as 0.16 U L-1. Furthermore, the probe shows very good biocompatibility, which is beneficial for its application in biological systems.

Abstract
Fluorescent probes are powerful tools for detecting and mapping the species of interest in vitro and in vivo. Although the probes always show high selectivity and sensitivity, they are usually affected by some factors, such as detecting conditions and the probe concentrations. Ratiometric fluorescent strategies, possessing advantage of low background noise, would solve the problem effectively and lead to a higher sensing performance. Thus, an ESIPT-based ratiometric probe (HBTP-mito) was developed on the basis of a phosphorylated 2-(2'-hydroxyphenyl)-benzothiazole derivative for the determination of ALP activity. HBTP-mito is water soluble and emits green fluorescence in TBS buffer due to the blockage of ESIPT. Upon the introduction of ALP, the phosphate ester of HBTP-mito was hydrolyzed and the ESIPT process was restored. Accordingly, the fluorescence at 514 nm decreases, while emission at 650 nm shows a "turn-on" response. The ratio of intensity (I514nm/I650nm) decreases linearly with ALP activity increasing from 0 to 60 mU/mL, obtained an LOD of 0.072 mU/mL. The favorable performance of the probe enables its application not only in the detection of ALP activity in biological samples, but also in the localization of the ALP levels in living cells and in vivo.

Abstract
Nanomaterial/aptamer assembly has been extensively explored in the detection of various targets, but some limitations still exist in its practical applications, especially time consumption and low-efficient detachment of the aptamer from the nanomaterial surface. In this work, we demonstrated the ligand role of pyrophosphate ion (PPi) in the competitive displacement of ssDNA from the nanoscaffold surface. For this purpose, a fluorescein-labeled ssDNA (F-DNA) and a mixed valence state cerium (Ce3+/Ce4+)-based MOF (MVCM) were employed as the signal response unit and nanoscaffold, respectively. Benefiting from the existence of Ce4+, the MVCM exhibits an ultrahigh quenching efficiency (more than 90%) to F-DNA fluorescence, which is 3-fold higher than that of the MOF with Ce3+ only. However, it was found that PPi can effectively suppress the quenching effect of the MVCM by competitive coordination with the MVCM to displace F-DNA. Different from the conventional target-induced conformational change of aptamers, the PPi-triggered displacement assay is independent of the ssDNA sequence and can be rapidly completed in just 2 min. The displacement assay is also highly sensitive, even at a PPi concentration as low as 55 nM. In contrast to PPi, however, the phosphate ions and other anions cannot displace F-DNA from the MVCM surface to switch on the F-DNA fluorescence. Inspired by this fact, the PPi-triggered displacement assay was further applied in the detection of alkaline phosphatase (ALP). The detection limit toward ALP was obtained at 0.18 mU mL-1. Moreover, the accurate determination of ALP concentration in serum samples indicates the applicability of this sensing system in detecting real samples.

Abstract
In this contribution a highly cost-effective flow analysis system for determination of alkaline phosphatase (ALP) activity is presented. This fully-mechanized bioanalytical system is based on economic solenoid micropumps and microvalves (powered and actuated by Arduino microcontroller) and extremely cheap dedicated optoelectronic flow-through detectors allowing absorbance and fluorescence measurements. The detection schemes for ALP assaying realized in this system are based on orthophosphate determination. For the detection of these ions formed in the course of enzymatic conversion a molybdate method requiring only common and inexpensive chemicals is utilized. Thus, for the enzymatic assays the simplest not-chromogenic/not-fluorogenic ALP substrates can be applied. Such approach results in the use of low-cost reagents for ALP assays, whereas the mechanization of assay causes low consumption of reagents as well as samples. In the course of reported investigations six ALP substrates were examined and the most promising results have been obtained for the inorganic compound - monofluorophosphate (MFP). The obtained linear ranges of absorbance and fluorescence measurements are 100-600 U L-1 and 30-30/30-100 U L-1, with sensitivities of 0.7 mV L-1 U-1 and 2.3/1.0 mV L-1 U-1, respectively. The calculated limits of detection are 5.1 U L-1 (photometry) and 0.9 U L-1 (fluorometry). The throughputs of the developed system are 13 and 12 samples/h for photometric and fluorometric detections, respectively. To demonstrate the practical utility of the developed bioanalytical system the ALP assays in complex matrix samples have been carried out. The results of ALP activity determination in serum samples are well-correlated with those obtained using reference method recommended for routine clinical analysis.

Abstract
We describe the characterization and application of quercetin pentaphosphate (QPP), a new fluorimetric substrate for the detection of alkaline phosphatase (ALP) activity. QPP exhibits major absorbance peaks at 260/410 nm and a strong fluorescence at λex/λem = 425/510 nm at alkaline pH. The product of enzymatic reaction between QPP and ALP has a strong absorbance peak at 324 nm with no fluorescence at the investigated wavelengths. The product generated from the enzymatic reaction was found to be proportional to ALP activity, and the ALP activity was monitored by the absorbance difference at 310 nm and 410 nm. The change in absorbance was found to be proportional to the ALP concentration with a linear detection range and a limit of detection of 0.01-16 U L(-1) and 0.766 U L(-1), respectively. The enzyme activity was also monitored by evaluating the change in fluorescence emission at 530 nm with a linear range of 0.01-8 U L(-1) and a detection limit of 0.062 U L(-1). Further, the validity of the new substrate for ALP in conjugated form was tested using Bacillus globigii spores as the model sample. A detection limit of 5998 spores per mL was obtained using QPP as the substrate. Unlike the parent compound, QPP substrate exhibits stability in solution for over three and half months and was stable under storage for over 12 months. The results obtained demonstrate the effectiveness of QPP for ALP and compare well with other fluorescent substrates, such as Fluorescein, Alexa Fluor and Cy5.

Abstract
Rhodamine S could emit strong and stable room temperature phosphorescence (RTP) on polyamide membrane (PAM) in the presence of heavy atom perturber Pb(2+). When Rhodamine S-piperidine solution was dropped on PAM, the red (Rhod.S)(n)-P-SOR (Rhod.S, (Rhod.S)(n), P and SOR refer to alizarin red S, multiple Rhod.S molecules, piperidine and self-ordered ring, respectively) formed on PAM, leading to the enhancement of room temperature phosphorimetry (RTP) intensity (I(p), 117.2) of (Rhod.S)(n)-P-SOR system, which was 2.4 times higher than that without SOR (I(p), 48.1). Wheat germ agglutinin (WGA) was labelled with (Rhod.S)(n)-P-SOR by the -NH- of Rhod.S reacting with the -COOH of WGA to form WGA-(Rhod.S)(n)-P-SOR. The formation of WGA-AP-WGA-(Rhod.S)(n)-P-SOR in the affinity adsorption (AA) reaction carried out between the -COOH of WGA in WGA-(Rhod.S)(n)-P-SOR and the -NH(2) of alkaline phosphatase (AP) caused the RTP intensity (ΔI(p)) of the WGA-AP-WGA-(Rhod.S)(n)-P-SOR system 7.8 times larger than that without (Rhod.S)(n)-P-SOR. Therefore, the coupling technique of SOR and solid substrate-room temperature phosphorimetry (SS-RTP) for the determination of trace AP has been established. This method possessed good selectivity, high sensitivity (Detection limit (L.D) was 3.4×10(-16)gmL(-1)) and accuracy, and it has been applied to the determination of trace AP in human serum and the forecast of human diseases, and the results agreed well with those obtained by enzyme-linked immunoassay (ELISA). Besides, the mechanism of the coupling technique for the determination of AP was discussed.

Abstract
A convenient method to synthesize disodium salt of 2-(5-phenyl-1, 3, 4-oxadiazol-2-yl) phenyl phosphate (OXDP), a substrate for the fluorescent determination of alkaline phosphatase (ALP) activity, via an one-pot procedure of condensation between the benzoic acid and 2-hydroxybenzhydrazide at triethylamine alkaline solution in the presence of propylphosphonic anhydride, was realized. Preliminary tests reveal that the lessened fluorescence intensity resulting from enzyme reaction is proportional to ALP activity in the range of 1.0-25.0 U/L with the detection limit of 0.25U/L, which can be successfully applied to assess ALP in human serum with good precision.
