A rapid colorimetric method for the detection of deltamethrin based on gold nanoparticles modified with 2-mercapto-6-nitrobenzothiazole

In this study, we developed a rapid colorimetric method for the detection of deltamethrin using gold nanoparticles modified with 2-mercapto-6-nitrobenzothiazole (Au NPs-MNBT): deltamethrin adhered onto the surface of Au NPs-MNBT and a core-shell structure formed with Au NPs-MNBT as the core and deltamethrin as the shell. The formation of the core-shell structure caused the change of solution color and UV-visible absorption spectra of Au NPs, which can be used to quantitatively detect deltamethrin by the naked eye and using a UV-Vis spectrophotometer. The effect of MNBT content, detection pH and reaction time on the detection of deltamethrin was studied in detail, and the selectivity and anti-interference ability of the probe were tested. The results showed that the probe can be used to detect deltamethrin rapidly and accurately from 13 kinds of other pesticides. The detection of deltamethrin was not affected when 5 times the concentration of other pesticides coexisted with deltamethrin. The detection limit of deltamethrin was observed to be 0.25 muM by the naked eye and 0.005 muM by UV-Vis spectroscopy. The extract solutions of small tomato and cherry were used to evaluate the feasibility of this detection method in actual samples and the results were consistent with that of gas chromatography-mass spectrometry, which proved that the developed method has actual sample application potential for deltamethrin detection.

Creation and imitation of a milk flavour

Flavour plays a crucial role in food and is the most important aspect of milk. Milk has a pleasant smell and milk flavour can be used in several products. However, how to recreate milk flavour has rarely been reported. Therefore, the creation of milk flavour is of great interest. This study focused on the creation and imitation of milk flavour. The approach to flavour creation involves identifying the attributes of the flavour and developing an impactful, authentic flavour. Accordingly, to create a milk flavour, the notes of milk flavour were identified by smelling and tasting milk. Based on the identified notes, aroma ingredients were selected to blend into a milk-flavour. After olfactory discrimination, several modifications and adjustments were made and a typical milk flavour formula was obtained. The results showed that the milk flavour has the following notes: milky, acidic, vanilla-like, caramel-like, aldehydic, fruity, beany, buttery, meaty, and vegetative. Lactones, acids, aldehydes, alcohols, ketones, esters, sulphur compounds, furans, and nitrogen compounds can provide these notes. Based on the developed formula, a harmonious flavour with typical characteristics of milk was obtained by blending the selected aroma ingredients.

Discovery and Optimization of Small Molecule Splicing Modifiers of Survival Motor Neuron 2 as a Treatment for Spinal Muscular Atrophy

The underlying cause of spinal muscular atrophy (SMA) is a deficiency of the survival motor neuron (SMN) protein. Starting from hits identified in a high-throughput screening campaign and through structure-activity relationship investigations, we have developed small molecules that potently shift the alternative splicing of the SMN2 exon 7, resulting in increased production of the full-length SMN mRNA and protein. Three novel chemical series, represented by compounds 9, 14, and 20, have been optimized to increase the level of SMN protein by >50% in SMA patient-derived fibroblasts at concentrations of <160 nM. Daily administration of these compounds to severe SMA Delta7 mice results in an increased production of SMN protein in disease-relevant tissues and a significant increase in median survival time in a dose-dependent manner. Our work supports the development of an orally administered small molecule for the treatment of patients with SMA.

Capture-Tag-Release: A Strategy for Small Molecule Labeling of Native Enzymes

A strategy for labeling native enzymes in a manner that preserves their activity is reported: capture?tag?release (CTR). Key to this approach is the small molecule CTR probe that contains an enzyme inhibitor, benzophenone crosslinker, and aryl phosphine ester. After UV-derived capture of the enzyme, addition of an azide-containing tag triggers a Staudinger ligation that labels the enzyme. A further consequence of the Staudinger ligation is fragmentation of the CTR probe, thus releasing the inhibitor and restoring enzymatic activity. As a proof-of-principle, the CTR strategy was applied to the hydrolase beta-galactosidase. The enzyme was efficiently labeled with biotin, and the kinetic data for the biotinylated enzyme were comparable to those for unlabeled beta-galactosidase. The CTR probe exhibits excellent targeting specificity, as it selectively labeled beta-galactosidase in a complex protein mixture.

Graphitic carbon nitride and polymers: A mutual combination for advanced properties

The sheet-like material graphitic carbon-nitride (g-C3N4) is one of the most promising metal-free photocatalysts and utilized for various purposes, e.g. energy conversion, waste water remediation or organic synthesis. g-C3N4 features a suitable band gap in the visible light range and outstanding physicochemical stability. However, g-C3N4 features drawbacks such as structural disorder, low conductivity, poor dispersibility and in turn low processability. Amongst the strategies to improve g-C3N4 properties, combination with polymers is a promising avenue toward advanced materials. The present critical review highlights the development and investigation of g-C3N4/polymer combination, including (1) g-C3N4 as photoinitiator for polymer snythesis, (2) polymer modified g-C3N4 for improved dispersibility, (3) g-C3N4/polymer hybrid materials fabricated via physical or covalent attachment and (4) g-C3N4 based hydrogels. The fabrication methods and application of these areas will be critically reviewed and the advantage of g-C3N4/polymer combination comprehensively presented. Moreover, the broad range of applications is highlighted, e.g. photocatalysis, batteries, biosensors, H2 evolution and films. Finally, the review will conclude with a summary and perspective on future directions as well as current challenges of this research area in order to stimulate new research regarding the design and construction of g-C3N4/polymer materials.

Microwave-assisted extraction and differential scanning calorimetry in the chemical identification of sliming agents apprehended in the south region of Brazil

Over the past decades, consume of slimming agents considerably increased in several countries, including Brazil, due to weight-loss and stimulant properties. Since these drugs are controlled to prevent illicit and indiscriminate use, there is a parallel illegal market that uses the Internet and irregular pharmacies in order to distribute these formulations. Slimming agents produced by these illegal sources are known for being manufactured with little or none quality control resulting in uncertain and unknown formulations. For forensic purposes, apprehended pharmaceuticals have to undergo a process of chemical identification that can be difficult due to its complex matrix. In this sense, application of assisted energies in the extraction step such as microwave irradiation can be a promising method to increase the recuperation of the target molecules of the sample. Therefore, the aim of this research was to identify four slimming agents apprehended in Brazil by means of visual inspection, Fourier Transform Infrared Spectroscopy, Differential Scanning Calorimetry and Gas Chromatography ? Mass Spectrometry. Moreover, the efficiency of solid-liquid extraction and microwave-assisted extraction was compared. It should be noted that our work was one of the few to use Differential Scanning Calorimetry and the application of microwave irradiation in the analysis of apprehended materials. Results showed that the majority of the samples was counterfeit being composed of one or several adulterants or contaminants. Initially, visual inspection resourcefully screened the slimming agents for possible signs of falsification, however it failed to detect fraudulent products that were very similar to veridical medicines. Sequentially, Fourier Transform Infrared Spectroscopy detected functional groups present in the samples while the presence or absence of the alleged active ingredients were successfully measured with Differential Scanning Calorimetry and, thus, providing a full chemical screening of the apprehended materials. Gas Chromatography- Mass Spectrometry confirmed the presence of adulterants such as caffeine, fluoxetine and phenolphthalein as well as contaminants such as sulfurol in the falsified samples. Finally, comparison of extraction procedures indicated that microwave-assisted extraction increased the recovery of compounds detected in chromatographic analysis to a greater extent than solid-liquid extraction.
