ABSTRACT A novel visual detection method was developed for H2O2 and glucose detection via the L-Cysteine (L-Cys) mediated synthesis of quantum dots (QDs). The mechanism of the ligand effect during QDs synthesis was also studied by theoretical calculation. This strategy is based on that L-Cys can be used as both H2O2 substrate and ligand to mediate biomimetic synthesis of luminescent CdTe QDs. Iodide (I-) can catalytic oxidized L-Cys to L-cystine in the presence of H2O2, which inhibits the synthe...

Abstract Continuous biochemical monitoring with a flexible electrochemical sensor offers a new wearable electronic system that can measure real-time voltage and current signals. The signal quality is determined by long-term stability of a silver/silver chloride reference electrode (Ag/AgCl RE). However, it is very challenging for any solid-state electrode to have a long-term stable operation. Even though new membrane technologies have improved the voltage stability, the existing thin film Ag/AgC...

Abstract Determination of circulating cancer cells in human blood is potential to be convenient diagnosis of different cancers. The study reports one strategy for synthesis of folic acid and glutamic acid-functionalized graphene quantum dot-palladium@gold (FA/Glu-GQD-Pd@Au). Firstly, FA/Glu-GQD was prepared by thermolysis of the mixture of citric acid, glutamic acid and folic acid. Then, it was used as the stabilizer and reducer for synthesis of FA/Glu-GQD-Pd@Au. The resulting hybrid was employe...

Abstract A one-step method assisted by hydrothermal treatment was approached to obtain nanocrystalline 1 and 10 mol.% In doped 2 mol.% Pd-SnO2 powders using a non-ionic surfactant Brij52 and Polyethylene glycol 6000 (PEG) as templates. Depending on In content, the samples were labeled as Pd1InSn and Pd10InSn. The obtained materials consist of nanosized crystallites packed into micrometric grains with a high porosity, as revealed by the morphological and structural investigations (SEM, TEM). A de...
Abstract In this work, an innovative drug delivery system based on cyclic RGD-modified (as the targeting agent) and doxorubicin-loaded graphene quantum dots (R–GQDs@DOX) was fabricated for chemo-photothermal combination therapy. These tasks include drug loading capacity, photothermal efficiency, cellular uptake and combination therapeutic effect of R–GQDs@DOX. The structure of R–GQDs@DOX was characterized by FT-IR spectrum, UV-vis spectrum and AFM. The results indicated that the doxorubicin (DOX...

Abstract Protein S-nitrosylation is an important post-translational modification, which has important effect on protein functions and is relevant to various diseases. For quantification of the S-nitrosated proteins, it is still challenging to establish a detection method in combination of fast and one-step determination, highly sensitivity and accuracy. Here, we develop a label-free, direct detection method for S-nitrosated proteins based on resonance Raman scattering of ferrous cytochrome c. Th...

Abstract Different from the dominant method of surface modification of metal oxide sensing materials with noble metals, a simple and low-cost method is developed by using Zn nanoparticles as a surface modifier in this work. The first step involves the fabrication of porous In2O3 nanofibers by an electrospinning technique, and then Zn nanoparticles decorated In2O3 nanofibers are constructed by a simple thermal evaporation method. An increase in surface O 2 - species absorbing capability and a dec...

Abstract Electronic tongues have been identified as useful tools for quantifying the taste of food and beverages. However, the bitterness evaluation of coffee in the presence of high-potency sweeteners has not been performed yet. In this study, we investigated an approach to quantify the bitterness of coffee with different roasting degrees and the sweetness of acesulfame potassium (Ace K) added to the coffee using taste sensors with lipid polymer membranes. A formula for predicting coffee bitter...

Abstract For achieving the high-performance film bulk acoustic resonator (FBAR) humidity sensor with MEMS process reliability, we proposed a novel FBAR design based on the polyimide film (PI-FBAR). The PI film was employed to provide multifunction for the structural supporting and humidity sensing simultaneously, which was first used in the back-trench FBAR. Due to its flexible and low acoustic impedance characters, it can provide adequate structural robustness and high quality factor (Q=210). A...

Abstract The evolution of hydrogen gas from corroding magnesium arises not exclusively from the cathodic half-cell reaction due to the consumption of the electrons released by the dissolving metal, but anodized magnesium generates significant amounts of H2 gas as well. In addition, the increase of the anodic overpotential enhances the rate of hydrogen gas generation. Therefore, spatially-resolved detection of the actual sites for hydrogen evolution related to anodically-activated sites is attemp...
