Site-selective cation-pi interaction as a way of selective recognition of the caesium cation using sumanene-functionalized ferrocenes

The first sumanene-ferrocene probes for efficient and selective caesium cation (Cs+) recognition are reported. The working mechanism of the sumanene moiety as the sensing unit was based on the site-selective cation-pi interaction in its neutral state. The interactions with Cs+ were characterized by high association constant values together with low limits of detection.

Nanoscale Electrochemical Sensing and Processing in Microreactors

In this review, we summarize recent advances in nanoscale electrochemistry, including the use of nanoparticles, carbon nanomaterials, and nanowires. Exciting developments are reported for nanoscale redox cycling devices, which can chemically amplify signal readout. We also discuss promising high-frequency techniques such as nanocapacitive CMOS sensor arrays or heterodyning. In addition, we review electrochemical microreactors for use in (drug) synthesis, biocatalysis, water treatment, or to electrochemically degrade urea for use in a portable artificial kidney. Electrochemical microreactors are also used in combination with mass spectrometry, e.g., to study the mimicry of drug metabolism or to allow electrochemical protein digestion. The review concludes with an outlook on future perspectives in both nanoscale electrochemical sensing and electrochemical microreactors. For sensors, we see a future in wearables and the Internet of Things. In microreactors, a future goal is to monitor the electrochemical conversions more precisely or ultimately in situ by combining other spectroscopic techniques.

A simple microdroplet chip consisting of silica nanochannel-assisted electrode and paper cover for highly sensitive electrochemiluminescent detection of drugs in human serum

This paper describes a simple and miniaturized microdroplet chip (muchip) that is constructed with a silica nanochannel (SNC)-assisted electrode array and a hydrophobic paper cover (SNC&P-muchip). Vertically aligned SNCs with uniform pore size of 2?3 nm in diameter and negatively charged surface can significantly accelerate the mass transport of the positively charged tris(2,2′-bipyridyl) ruthenium (II), resulting in a remarkably enhanced electrochemiluminescence (ECL) signal. The SNC-assisted electrode array was coupled to a low cost paper cover to achieve simultaneous detection of six samples in 1 min. The feasibility and universality of the SNC&P-muchip was evaluated by detecting a series of alkaloidal drugs both in buffers and in human serum. The performance of the SNC&P-muchip was fully validated with respect to linearity (0.9999 > R > 0.9939), sensitivity (limits of detection from 1.799 nM to 11.43 nM), and accuracy (recovery rate between 94.38% and 109.12%). The facile and economic SNC&P-muchip shows promising potential for rapid drug detection in complex biofluids.

Voltammetric sensing of biomolecules at carbon based electrode interfaces: A review

Biomolecules are integral constituents of living beings which regulate numerous biochemical functions of the body. Analysis of various small molecules (metabolites, neurotransmitters, amino acids, vitamins) and macromolecules (nucleic acids, proteins) is of prime importance in modern time due to increasing disbalance in natural metabolism of human body. Irregularities and alteration in concentration of biomolecules lead to different kinds of genetic, metabolic and cancerous diseases which have created a great requirement of highly sensitive, accurate and stable detection systems for their quick and specific screening. In this review, redox interactions of biomolecules at carbon based electrode interfaces have been discussed using voltammetry. It is divided into subsections, starting with an introduction into the field and a description of its current state. This is followed by a large section describing carbon nanomaterials (CNs) based voltammetric sensors for different small biomolecules and macromolecules. The next section of the review gives conclusion, challenges and future perspectives in sensing biomolecules at CNs based electrodes. Advanced approaches for fabrication of portable integrated electrochemical devices for various point of care diagnostic applications have also been included at the end.

Analysis of the binding of bovine and human fibrinogen to ferritin: Evidence that fibrinogen is a common ferritin-binding protein in mammals

Both human and horse fibrinogen are heme-binding proteins, and horse fibrinogen also exhibits heme-mediated ferritin binding. This study found that bovine and human fibrinogen are heme-mediated ferritin-binding proteins and demonstrated direct binding of bovine ferritin to protoporphyrin (PPIX) and its derivatives or to Zn ions. Binding of bovine and human fibrinogen to bovine spleen ferritin coated on microtiter plate wells was detected using an anti-human fibrinogen antibody, and this binding was inhibited in a dose-dependent manner by hemin (iron-PPIX) and also inhibited by Zn-PPIX. PPIX showed less of an inhibitory effect on the binding of bovine and human fibrinogen to bovine ferritin. The inhibitory effect of Sn-PPIX was similar to that of PPIX, but with respect to human fibrinogen, PPIX did not inhibit the binding of human fibrinogen to ferritin. Bovine fibrinogen immobilized on CNBr-activated Sepharose 4B beads showed affinity for hemin, Sn-PPIX, Zn-PPIX, and iron-free PPIX in the order Sn-PPIX < iron-free PPIX < hemin < Zn-PPIX. The fibrinogen beads also directly bound to zinc ions. These results suggest that bovine fibrinogen is a heme- and zinc-binding protein and that binding of circulating mammalian fibrinogen to ferritin is heme mediated.

Development of an electrode-membrane-electrode system for selective Faradaic response towards charged redox species

We investigate the Faradaic currents of ferrocene species at an electrode-membrane-electrode system. The membrane electrodes system is fabricated by physical sputtering of conductive metal on both sides of a nanoporous alumina membrane. The metal coatings function as working electrodes by connection to a bipotentiostat and reference/counter electrodes in the sample solution. Collection and shielding efficiency studies are carried out at this membrane electrodes system to measure mobility values of charged ferrocene species within nanochannels of alumina membrane. Results indicated high selective electrode response of up to 16 times for positively charged (dimethylaminomethyl)ferrocene (FcN), and neutral ferrocenemethanol (FcMeOH), compared to the negatively charged ferrocenecarboxylic acid (FcCOOH) when the receiver electrode was maintained at negative potentials of 0.5-1.0 V relative to the feed electrode. This is a report on the use of an electrode-membrane-electrode system to achieve selective response towards differently charged redox species, under the condition of high electrolyte concentration (0.1 M, pH 7.0 phosphate buffer).

Synthesis and reactivity of unsymmetrical azomethine imines formed using alkene aminocarbonylation

Complex cyclic azomethine imines possessing a beta-aminocarbonyl motif can be accessed readily from simple alkenes and hydrazones. This alkene aminocarbonylation approach allows formation of ketone-derived azomethine imines of unprecedented complexity. Since unsymmetrical hydrazones are used, two stereoisomers are formed: the reactivity of chiral derivatives is explored in both intra- and intermolecular systems.
