This study demonstrates a new unlabeled immobilized DNA–based biosensor with ordered mesoporous carbon nitride material (MCN) for detection of Ag+ by electrochemical impedance spectroscopy (EIS) with [Fe(CN)6]4–/3– as redox couple. The unlabeled immobilized DNA initially formed the hairpin ...

A new in vitro assay was developed to detect human epidermal growth factor receptor 2 (HER2) protein based on affinity dissociation of carbon nanotube (CNT)-wrapped anit-HER2 ssDNA aptamers. First, we selected an anti-HER2 ssDNA aptamer (H2) using an in vitro Serial Evolution of Ligands by ...

Platinum (Pt) nanoparticles with <4 nm diameter loaded on graphitic carbon nitride (g-C3N4) by reduction at 673 K behave as efficient co-catalysts for photocatalytic hydrogen evolution under visible light (λ

A novel methodology is presented for the direct methylation of amines, using formic acid as a unique source of carbon and hydrogen. Based on ruthenium(ii) catalysts, the formation of the N–CH3 group proceeds via an efficient formylation/transfer hydrogenation pathway.

Aromatic amphiphiles were self-assembled into 2-D nanosheets and 1-D nanofibers by systematically varying the volume fraction of the hydrophilic coils, which enabled the direct exfoliation of carbon allotropes with high quality and quantity. A 2-D nanosheet structure was introduced as the hole ...

Fluorescent carbon nanoparticles or carbon quantum dots (CQDs) are a new class of carbon nanomaterials that have emerged recently and have garnered much interest as potential competitors to conventional semiconductor quantum dots. In addition to their comparable optical properties, CQDs have the ...

A new approach to normalize measured isotope ratios (carbon and nitrogen) in elemental analyser continuous flow isotope ratio mass spectrometry (EA-CF-IRMS) was evaluated. Isotope ratios of the sample are altered during the IRMS measurement and must be corrected for instrumental isotope ...

The direct electrophilic α-cyanation of β-keto esters and amides has been developed using hypervalent iodine benziodoxole-derived cyano reagent. It accomplishes within 10 min without any catalyst in DMF at room temperature. Thus, the highly functionallized quaternary carbon-centered nitriles were ...

Here we report a low-cost and facile synthesis approach for carbon-doped mesoporous anatase TiO2 by using Ti(BuO)4 as a source for both Ti and carbon through xerogel carbonization in a hypoxic atmosphere. The resultant mesoporous C-TiO2 with high crystallinity exhibits excellent photocatalytic ...
