A bright idea: 15-fold increase in fluorescence intensity occurs when the complex formed between Eu3+ and antibiotic tetracycline binds to hydrogen peroxide at neutral pH. The can be used determination of concentration H2O2, activity oxidases, glucose, also an optical sensor for H2O2.
Abstract A variety of nanomaterial‐based biosensors have been developed to sensitively detect biomolecules in vitro, yet limited success has achieved real‐time sensing vivo. The application microneedles (MN) may offer a solution for painless and minimally‐invasive transdermal biosensing. However, integration nanostructural materials on microneedle surface as electrodes remains challenging applications. Here, H 2 O electrochemical biosensor based MNs integrated with nanohybrid consisting...
Real-time transdermal biosensing provides a direct route to quantify biomarkers or physiological signals of local tissues. Although microneedles (MNs) present mini-invasive technique, integration MNs with advanced nanostructures enhance sensing functionalities has rarely been achieved. This is largely due the fact that on surface could be easily destructed friction during skin insertion. In this work, we reported dissolvable polymer-coating technique protect nanostructures-integrated from...
Getting the picture: Citrate and other intermediates of citric acid cycle can be imaged by time-resolved fluorescence with a Eu3+ tetracycline complex as fluorescent probe (see picture). The time resolution enables discrimination between intermediates, enzymatic conversions are not needed.
Four novel ruthenium(<sc>ii</sc>) complexes have been characterized for the colorimetric and luminescent bi-functional sensing of cyanide ions. The structure one complex is also determined by single crystal X-ray diffraction.
Bioactive functional probiotics play an important role in many health applications such as maintaining skin and the immunity of human host. Artificial supplementation would enhance immune functions well regulate health. However, simple effective methods to deliver into dermis local dermal tissue are still lacking. Furthermore, microneedles have been used for transdermal drug delivery a pain-free manner, yet there were few reported living microbes via microneedles. In this work, we developed...
A new type of fluorescence assay for the determination peroxidase (POx) activity is presented. The based on indication enzymatic consumption H(2)O(2) (HP), using a fluorescent europium-tetracycline (Eu(3)TC) complex as indicator. On addition HP, this forms highly adduct (Eu(3)TC-HP), which decomposed in presence POx to form weakly (Eu(3)TC). Hence, enzyme can be directly determined by means luminescent Eu(3)TC demonstrated herein was elaborated starting from spectral characterization systems...
Ein Anstieg der Fluoreszenzintensität um den Faktor 15 tritt ein, wenn Wasserstoffperoxid zu dem Eu3+-Tetracyclin-Komplex in einer Pufferlösung von pH 6.6–7.2 gegeben wird (siehe Bild; A=Absorbanz, F=Fluoreszenzintensität). Der Komplex kann somit als Fluoreszenzsonde zur Bestimmung H2O2- und D-Glucose-Konzentrationen, Oxidaseaktivitäten sowie optischer Sensor für H2O2 eingesetzt werden.
Wir haben ein Bild! Citrat und andere Zwischenstufen des Citrat-Zyklus lassen sich durch zeitaufgelöste Fluoreszenzspektroskopie unter Verwendung eines Eu3+-Tetracyclin-Komplexes als Fluoreszenzsonde bildlich darstellen (siehe Bild). Die zeitliche Auflösung ermöglicht die Unterscheidung verschiedener ohne den Einsatz von Enzymen.
Abstract Chiral discrimination of malates in aqueous solutions at near‐neutral pH is achieved through fluorescence measurement and imaging using the europium–tetracycline complex (EuTc) as a fluorescent probe. The method based on significantly different properties ternary complexes (Eu–Tc–malate) formed between EuTc enantiomeric malates. excess (ee) chiral can be quantified by both steady‐state time‐resolved fluorescence, either conventional microplate reader or imaging. It offers facile...
Summary The clastic reservoir in Tahe oil field, west China, is characterized by thin sandstone thickness and low seismic resolution, which brings difficulty to sand description. To solve this problem, we present a resolution enhancement method prediction detect bed reservoir. We improve based on the matching pursuit (MP) algorithm. original data decomposed into superposition of many best-matched wavelets using MP Then increase amplitudes at high frequencies with signal-noise ratio, while...
