CuO nanowires have been prepared and applied for the fabrication of glucose sensors with highly enhanced sensitivity. Cu(OH)(2) were initially synthesised by a simple fast procedure, then formed simply removing water through heat treatment. The structures morphologies characterised X-ray diffraction, photoelectron spectroscopy, scanning electron microscopy, transmission microscopy. direct electrocatalytic oxidation in alkaline medium at nanowire modified electrodes has investigated detail....
This paper reports for the first time electrogenerated chemiluminescence (ECL) behavior of graphite-like carbon nitride (g-C(3)N(4)) with K(2)S(2)O(8) as coreactant. The possible ECL reaction mechanisms are proposed. spectral features emission and photoluminescence (PL) g-C(3)N(4) compared, their resemblance demonstrates that excited states from both photoexcitation same. effects concentration, pH, g-C(3)N(4)/carbon powder ratio, scan rate on intensity have been studied in detail....
Innovative phosphorus and nitrogen dual-doped hollow carbon dots (PNHCDs) have been fabricated for anticancer drug delivery biological imaging. The functional groups of PNHCDs are introduced by simply mixing glucose, 1,2-ethylenediamine, concentrated phosphoric acid. This is an automatic method without external heat treatment to rapidly produce large quantities PNHCDs, which avoid high temperature, complicated operations, long reaction times. as-prepared possess small particle size,...
The synthesis of water-soluble near-infrared (NIR)-emitting quantum dots (QDs) in aqueous solution has received much attention recently. However, the stabilizer 3-mercaptopropionic acid, commonly used NIR-emitting QDs, is notorious for its toxicity and awful odor. Here we chose thiol ligand N-acetyl-l-cysteine (NAC) as ideal have successfully employed it to synthesize high-quality CdTe/CdS QDs a one-step process via simple hydrothermal route. NAC possesses favorable properties such nontoxic,...
Phosphorous and nitrogen co-doped carbon dots (P,N-CDs) with satisfactory quantum yield have been prepared through one-step acidic oxidation of pumpkin by H3PO4 at low temperature (90 °C). The as-prepared P,N-CD is relatively monodisperse a narrow size distribution. displays remarkable emission enhancement in the yellow fluorescence region (λem = 550 nm) when pH increased from 1.5 to 7.4. pKa value P,N-CDs was found be 4.17 it shows linear response physiological range 4.7-7.4, which valuable...
A microwave (MW)-assisted synthesis method for preparation of fluorescent BSA-stabilized and HSA-protected gold nanoclusters (BSA–AuNCs HSA–AuNCs) has been developed. The reaction time can be shortened from tens hours to several minutes, thanks the superheating non-thermal effects MW energy. optimal experimental conditions including concentrations BSA, HAuCl4 NaOH programme are investigated in detail. as-synthesised BSA–AuNC product is well characterized by UV-vis spectroscopy, fluorescence...
A novel facile and template-free method to prepare a nanoball-like NiOx material has been developed. The preparation involves the synthesis of an α-Ni(OH)2 precursor by microwave heating calcination precursor. possesses structure with large surface area. pseudo-capacitive properties were evaluated cyclic voltammetry electro-chemical impedance spectroscopy in 6 M KOH solution. specific capacitances 951, 796, 713 650 F g−1, corresponding scan rates 2.0, 5.0, 10 20 mV s−1, respectively. also...
A green approach to synthesise nitrogen/sulfur co-doped carbon dots has been developed and the product was successfully analysed by HPLC.
An as-synthesised hollow carbon nanoparticle (HC-NP) sample has been proved to be a relatively complex mixture, and its complexity can reduced significantly by high-performance liquid chromatography. unprecedented reduction in such reveal fractions of HC-NP with unique luminescence properties. While the UV-vis absorption profile for mixture is featureless, do possess bands specific emission wavelengths. The are fully anatomised matrix-assisted laser desorption/ionisation time-of-flight mass...
Carbon nanodots (C-dots) are recently discovered fluorescent carbon nanoparticles with typical sizes of <10 nm. The C-dots have been reported to excellent photophysical and chemical characteristics. In recent years, the advances in development improvement synthesis, characterization, applications burgeoning. this review, we introduce most commonly used techniques for characterization C-dots. briefly classified, described, illustrated applied examples. addition, analytical separation...
An easy and simple two-step reaction is employed to synthesise a new type of ligand-protected (homocysteine-protected) gold-coated iron oxide nanoparticle (homocys-Au-Fe3O4). Fe3O4 nanoparticles are used as the central core prepare homocys-Au-Fe3O4 in aqueous state without precipitation aggregation nanoparticles. initially prepared subsequently coated with Au layers under hot citrate reduction HAuCl4. The monolayer then ready for place-exchange homocysteine molecules produce well dispersed...
