Fabrication and characterization of a bidirectional valveless peristaltic micropump and its application to a flow-type immunoanalysis

A planar bidirectional valveless peristaltic micropump for controlling biological sample fluids was designed with a very simple structure and fabricated employing MEMS technologies including deep reactive ion etching (DRIE) process in silicon, chemomechanical polishing (CMP), and silicon-glass anodic bonding. The proposed micropump was able to control the flow bidirectionally at the rate of ?12mul/min (20nl/stroke) for water and ?60mul/min (100nl/stroke) for air with an operation frequency of 10Hz at a voltage of 120Vpp. Actuation modeling of the PZT-glass actuator was performed using the CoventorWare, and the simulation results agreed well with the experimental measurements. In addition, the fabricated micropump was used in the setup for flow-type analysis and was found adequate in the electrochemical immunosensing by biocatalyzed precipitation.

Ferrocenes with simple chiral substituents: An in-depth theoretical and experimental VCD and ECD study

Circular dichroism spectra in the IR range (VCD = vibrational circular dichroism) and in the UV range (ECD = electronic circular dichroism) have been recorded for both enantiomers of simple mono-substituted ferrocenes containing chiral pendants: 1-acetoxyethylferrocene, 1, 1-methoxyethylferrocene, 2, and 1-hydroxyethylferrocene, 3; the related disubstituted 1,1?-bis(1-hydroxyethyl)ferrocene, 4, was also considered. These two types of spectra, with the support of DFT calculations, concur to unequivocally confirm the absolute configuration for 1-4. In particular, our computational results point out the clear advantage of using an anharmonic oscillator model for the interpretation of VCD spectra of chiral ferrocenes. Interesting conformational properties are either confirmed or established by the technique, like the eclipsed conformation of the two cyclopentadienyl rings and an intra-molecular interaction involving the OH for 3. For 4, NMR, VCD and IR spectra are compatible with dimer formation and in this case a distorted conformation is predicted. Of utmost importance for the absolute configuration assignment in mono-substituted ferrocenes, we were able to identify a diagnostic VCD band at 950 cm-1 and a (low intensity) ECD band that clearly indicate the absolute configuration of the whole series.

Effects of the redox group of carbazole-EDOT derivatives on their electrochemical and spectroelectrochemical properties

Three novel monomers based on carbazole-3, 4-ethoxylenedioxythiophene and redox groups were synthesized and characterized. Their polymer films were obtained by electropolymerization. Cyclic voltammetry and spectroelectrochemistry of the polymer films showed that they possessed multi-electrochromic property. The presence of ferrocene and 2,2,6,6-tetramethyl-1-piperidinyloxy units not only changed the films? colour but also improved their switching time due to their excellent electrochemical properties. Additionally, the polymer films also possessed a reasonable transmittance change, which made them promising candidates for use in electrochromic devices.

Electrons selective uptake of a metal-reducing bacterium Shewanella oneidensis MR-1 from ferrocyanide

The extracellular electron transfer of Shewanella oneidensis MR-1 (MR-1) has been extensively studied due to the importance of the biosensors and energy applications of bioelectrochemical systems. However, the oxidation of metal compounds by MR-1, which represents the inward extracellular electron transfer from extracellular electron donors into the microbe, is barely understood. In this study, MR-1 immobilized on an electrode electrocatalyzes the oxidation of [Fe(CN)6]4- to [Fe(CN)6]3- efficiently and selectively. The selectivity depends on midpoint potential and overall charge(s) of redox molecules. Among 12 investigated redox molecules, the negatively charged molecules with high midpoint potentials, i.e., [Ru(CN)6]4- and [Fe(CN)6]4-, show strong electrocatalysis. Neither reference bacteria (Escherichia coli K-12 nor Streptococcus mutans) electrocatalyze the oxidation of [Fe(CN)6]4-. The electrocatalysis decays when MR-1 is covered with palladium nanoparticles presumptively involved with cytochromes c. However, cytochromes c MtrC and OmcA on MR-1 do not play an essential role in this process. The results support a model that [Fe(CN)6]4- donor electrons to MR-1 by interacting with undiscovered active sites and the electrons are subsequently transferred to the electrode through the mediating effect of [Fe(CN)6]4-/3-. The selective electron uptake by MR-1 provides valuable and fundamental insights of the applications of bioelectrochemical systems and the detection of specific redox molecules.

Application of Biginelli reaction to the synthesis of ferrocenylpyrimidones and [3]-ferrocenophane-containing pyrimido[4,5-d]pyrimidinediones

A series of ferrocene-containing mono- and bis-dihydropyrimidines (DHP’s) were prepared by boric acid mediated three-component Biginelli reactions of formyl- and 1,1?-diformylferrocene, 1,3-dioxo-components and urea. A few further transformations including hydrogenolysis of a benzyl 4-ferrocenyl-DHP-5-carboxylate were also performed. Novel cis-fused saturated pyrimido[4,5-d]pyrimidine-2,7(1H,3H)-diones incorporating [3]-ferrocenophane moiety were constructed by means of iron(III)-catalyzed Biginelli-like condensations of 1,1?-diformylferrocene with urea and in situ generated methyl ketone-derived silyl enol ethers. The structures of the new compounds were established by IR and NMR spectroscopy, including HMQC, HMBC and DEPT measurements.
