A simple and sensitive fluorescence method for monitoring the activity inhibition of protein kinase (PKA) has been developed using polycytosine oligonucleotide (dC12)-templated silver nanoclusters (Ag NCs). Adenosine-5′-triphosphate (ATP) was found to enhance Ag NCs, while hydrolysis ATP adenosine diphosphate (ADP) by PKA decreased NCs. Compared existing methods assay, does not involve phosphorylation substrate peptides, which significantly simplifies detection procedures. The exhibits high...
Taking advantage of the protection effect single-stranded DNA oligonucleotides, gold nanoparticles (AuNPs) remain dispersed and retain a red color with addition low concentration salt, while AuNPs would aggregate in presence double-stranded DNA. This difference has been used to design label-free colorimetric sensors for detection. NaCl is most commonly salt induce aggregation AuNPs. In this work, we aimed test if other salts can provide even better sensor performance understand effects...
Poly-C DNA is highly efficient in etching silver nanoparticles followed by Ostwald ripening at high concentrations, increasing the toxicity of nanoparticles.
Dark tea, rich in nutricines including tea polyphenols and free amino acids, is a kind of post-fermented tea. The potential application against oxidative damage senescence, which drives animal health maintenance disease prevention, has attracted considerable interest. In this study, the effect dark its effects on longevity defense stress was investigated Caenorhabditis elegans ( C. ) model. Under normal conditions, extended lifespan without significant impairment propagation. It also...
In this paper, a simple strategy for the sensitive detection of hydroquinone (H2Q) using fluorescent silver nanoclusters (AgNCs) has been developed. presence H2O2 and peroxidase, fluorescence AgNCs was quenched efficiently by phenolic compounds. The mechanism inherent in quenching could be mainly ascribed to formation quinone intermediates via enzyme-catalyzed oxidation Combined with high specificity enzyme, method determine compounds linear relationship ranging from 8.0 × 10−8 3.2 10−6 mol...
A simple and efficient method for the fabrication of highly fluorescent platinum nanoclusters (Pt NCs) has been reported in which bovine serum albumin (BSA) serves as a scaffold NaBH<sub>4</sub> reductant.
A hybridization chain reaction (HCR)-based DNAzyme fluorescent sensor is demonstrated for <sc>l</sc>-histidine (<sc>l</sc>-His) assays.
Abstract Both affinity capillary electrophoresis (ACE) and fluorescence spectroscopy were used to measure the binding affinities between diclofenac sodium (DFS) bovine serum albumin (BSA) in this investigation. In ACE, DFS was injected into borate buffer containing various concentrations of BSA. Mobility ratio (M) deduce constant (K b ), which effectively eliminates effect electroosmotic flow (EOF). ACE measurements indicated two classes sites The K value for high (1.9 ± 0.2 × 105 M−1)...
Single-stranded DNA oligonucleotides have been widely used to functionalize metal nanoparticles, and the nanoparticles are often assumed be stable. We herein communicate that can both protect etch silver nanomaterials, such as triangular plates (AgTPs). For moieties with a high affinity Ag polycytosine (poly-C) polyguanine (poly-G), they display concentration-dependent etching, length was vital. Etching less effective when is folded into more compact structures. Polythymine (poly-T) adsorbed...
The Hg<sup>2+</sup> fluorescence sensor based on TdT isothermal amplification DNA templated CuNCs was successfully constructed.
While various DNA-functionalized nanomaterials and biosensors have been reported, most of them ignored the influence DNA on stability nanoparticles. We recently noticed that cytosine guanine rich oligonucleotides can etch silver nanoparticles (AgNPs). In this work, we communicated phosphorothioate (PS) modified (PS-DNA) could AgNPs quite independent sequence, suggesting thio modifications were playing major role etching. Compared to normal (e.g. poly-C DNA), required concentration decreased...
Abstract Anodic stripping voltammetry (ASV) has been combined on‐line with inductively coupled plasma‐mass spectrometry (ICP‐MS) using both Bi‐coated reticulated vitreous carbon (RVC) and glassy (GC) disk electrodes. Because the same flow cell is used for RVC GC electrodes, analytical performances between these two types of electrodes can be accurately compared their utilizations in ASV‐ICP‐MS technique. Comparison includes signal enhancement, reproducibility, dynamic range, hydrodynamic...
