“…Considering PL based biosensors, it is worth noting that the quenching of PL signal after target adsorption is being observed [62,68,[74][75][76][77]. The mechanism of PL quenching may be due to several reasons.…”

“…By measuring the decrease of the PL intensity, one can estimate the glucose concentration in solution. The sensor constructed by immobilizing GOx on ZnO nanoparticles enabled glucose to be continuously monitored in the 10 mM to 130 mM concentration range with the limit of detection 10 mM [68].…”

“…For instance, the change of both PL peaks intensities (near band emission (NBE) and deep level emission (DLE)) from ZnO nanoparticles was used separately as a signal for hydrogen peroxide (H2O2) and glucose detection by Sodzel et al [68]. Furthermore, an indirect optical determination of glucose via the detection of H2O2 generated during the glucose oxidase (GOx) catalyzed oxidation of glucose was performed.…”

“…H2O2, being in proximity, decomposes catalytically on the ZnO surface into H2O and O2. This reaction is followed by acceptance of electrons from the conduction band of ZnO, thus preventing its radiative recombination, and resulting in quenching of the light emission intensity [68]. Fig.4.…”

“…It is known, that ZnO has high value of isoelectric point (pH~9.1) [34,35,43,62,[66][67][68][69][74][75][76][77] which makes ZnO nanostructures attractive for immobilization of biomolecules on its surface. It is important to note that the morphology and the structure properties of ZnO play important role in the process of immobilization.…”

In this study, an enzyme‐coupled fluorescence sensor was developed successfully for the sensitive detection of uric acid (UA) and uricase inhibitor based on graphene quantum dots (GQDs). UA was first oxidized using uricase and produced hydrogen peroxide (H2O2), which could oxidize phenol to benzoquinone in the presence of horseradish peroxidase (HRP) as the catalysis. Benzoquinone is an efficient quencher and can cause fluorescence quenching of GQDs. The degree of quenching was proportional to UA concentration and was linear for the UA concentration in the ranges 0.2–14 μmol/L. The detection limit was 0.06 μmol/L for UA. In addition, the proposed sensor was further utilized for UA detection in human serum samples with satisfactory reproducibility and accuracy. The proposed strategy provided may be widely utilized to sense H2O2 or H2O2 generating processes in related biological environment.

Acrylamide (AA) is a carcinogenic, neurotoxin, and pregnancy‐harmful agent produced in food thermal processing. A specified excellent analytical technique performance is desired for detecting low AA concentration for human protection from its adverse impacts. A photoluminescent sensor APTES capped zinc oxide quantum dots (APTES/ZnO QDs) has been synthesized for AA quantification. Different capping agent's effects, for instance, triethanolamine (TEA), oleic acid (OA), tetraethyl orthosilicate (TEOS), polyvinyl pyrrolidone (PVP), 3‐aminopropyl triethoxysilane (APTES), and ethyl acetate (EA) on ZnO QDs are examined. The photoluminescence (PL) response of pristine ZnO QDs and APTES/ZnO QDs probe toward AA concentrations is investigated. This developed sensor exhibits selectivity as well as sensitivity for detecting AA ranging from 0.01 to 8.0 mM with a strong correlation coefficient (R2) of 0.9998 and a limit of detection (LOD) of 0.0019 mM, which is lesser than the WHO and European Union's guideline value. The possible photoluminescence enhancement mechanism of the APTES/ZnO QDs probe for AA detection is studied. Additionally, the reliability and performance of this facile, rapid, and precise analytical technique for quantifying AA in potato chip samples is confirmed and revealed satisfactory recoveries from 99.30 to 101.69% with relative standard deviations (RSD) from 1.4 to 1.6%.
