Microfabrication and Characterization of Solid Surfaces Patterned with Enzymes or Antigen-Antibodies by Scanning Electrochemical Microscopy

The microfabrication and characterization of glass surfaces patterned with enzymes (diaphorase, horseradish peroxidase(HRP)) or antigen-antibodies (carcinoembryonic antigen (CEA), human chorionic gonadotropin (HCG) and human placental lactogen (HPL)) were studied using scanning electrochemical microscopy (SECM). Localized enzymes and antigen-antibody complexes with labeled enzymes were characterized on the basis of detection of catalytic current for ferrocenylmethanol by SECM. The SECM technique was extended to the enzyme-linked immunosorbent assay (ELISA). This method detects as low as ? 104 CEA molecules in a single microspot. We also demonstrated a novel dual assay using microfabricated glass substrates with anti-HCG and anti-HPL microspots.

CO rebinding to protoheme: Investigations of the proximal and distal contributions to the geminate rebinding barrier

The rebinding kinetics of CO to protoheme (FePPIX) in the presence and absence of a proximal imidazole ligand reveals the magnitude of the rebinding barrier associated with proximal histidine ligation. The ligation states of the heme under different solvent conditions are also investigated using both equilibrium and transient spectroscopy. In the absence of imidazole, a weak ligand (probably water) is bound on the proximal side of the FePPIX-CO adduct. When the heme is encapsulated in micelles of cetyltrimethylammonium bromide (CTAB), photolysis of FePPIX-CO induces a complicated set of proximal ligation changes. In contrast, the use of glycerol-water solutions leads to a simple two-state geminate kinetic response with rapid (10-100 ps) CO recombination and a geminate amplitude that can be controlled by adjusting the solvent viscosity. By comparing the rate of CO rebinding to protoheme in glycerol solution with and without a bound proximal imidazole ligand, we find the enthalpic contribution to the proximal rebinding barrier, Hp, to be 11 ¡À 2 kJ/mol. Further comparison of the CO rebinding rate of the imidazole bound protoheme with the analogous rate in myoglobin (Mb) leads to a determination of the difference in their distal free energy barriers: DeltaGD ? 12 ¡À 1 kJ/mol. Estimates of the entropic contributions, due to the ligand accessible volumes in the distal pocket and the xenon-4 cavity of myoglobin (?3 kJ/mol), then lead to a distal pocket enthalpic barrier of HD ? 9 ¡À 2 kJ/mol. These results agree well with the predictions of a simple model and with previous independent room-temperature measurements (Tian et al. Phys. Rev. Lett. 1992, 68, 408) of the enthalpic MbCO rebinding barrier (18 ¡À 2 kJ/mol).

?Development and application of analytical detection techniques for droplet-based microfluidics?-A review

Droplet-based microfluidics has emerged as a powerful platform for high-throughput and low-volume analysis and screening. At present, droplet-based microfluidics is transitioning from the proof-of-concept stage to real-world applications. During this process, analytical detection techniques play indispensable roles for successfully implementing droplet-based chemical or biological assays. In this review, we provide an overview of recent developments in analytical techniques for droplet analysis and elucidate the advantages and limitations of each technique. We cover the majority of technology categories, including optical detection, electrical detection, mass spectrometry, and nuclear magnetic resonance spectroscopy. Additionally, we highlight new research areas that have been enabled by these technical advances. Finally, we provide perspectives on both future technological directions and potential enabling applications.

Photolysis of diacylferrocenes and their photo-ligand exchange reactions with 1,10-phenanthroline

The photolysis of 1,1?-diacylferrocenes Fc(COR)2 (Fc = Ferrocenyl, R = CH3,Ph) in the presence of 1,10-phenanthroline (phen) in deoxygenated acetonitrile under irradiation with visible light has been studied. In these photolysis systems the phen has two important roles to play: one is to stabilize the photo-liberated Fe2+ by coordination, and the other is to promote the photolysis through photo-ligand exchange. Under this condition the photoproducts were isolated in definite composition and characterized by single crystal X-ray diffraction, 1H NMR spectroscopy, IR spectroscopy, photolysis-cyclic voltammetry and elemental analysis. The mechanism of the reactions was demonstrated to be charge transfer from metal to acylcyclopentadienyl ring, leading to cleavage of the bond between them. The phen attacks the Fe2+ ion to give the stable tris (1,10-phenanthroline) iron(II) complex cation and the acylcyclopentadienyl ring detaches from the Fe2+ ion, giving the enolate anion in the outer sphere of the complex.

Electrochemical quantification of extracellular local H2O2 kinetics originating from single cells

Aims: H2O2 is produced by all eukaryotic cells under physiological and pathological conditions. Due to its enormous relevance for cell signaling at low concentrations and antipathogenic function at high concentrations, precise quantification of extracellular local hydrogen peroxide concentrations ([H2O2]) originating from single cells is required. Results: Using a scanning electrochemical microscope and bare platinum disk ultramicroelectrodes, we established sensitive long-term measurements of extracellular [H2O2] kinetics originating from single primary human monocytes (MCs) ex vivo. For the electrochemical techniques square wave voltammetry, cyclic and linear scan voltammetry, and chronoamperometry, detection limits for [H2O2] were determined to be 5, 50, and 500 nM, respectively. Following phorbol ester stimulation, local [H2O2] 5-8 mum above a single MC increased by 3.4 nM/s within the first 10 min before reaching a plateau. After extracellular addition of H2O2 to an unstimulated MC, the local [H2O2] decreased on average by 4.2 nM/s due to degradation processes of the cell. Using the scanning mode of the setup, we found that H2O2 is evenly distributed around the producing cell and can still be detected up to 30 mum away from the cell. The electrochemical single-cell measurements were validated in MC populations using electron spin resonance spectroscopy and the Amplex UltraRed assay. Innovation and Conclusion: We demonstrate a highly sensitive, spatially, and temporally resolved electrochemical approach to monitor dynamics of production and degradation processes for H2O2 separately. Local extracellular [H2O2] kinetics originating from single cells is quantified in real time.

First-and second-generation heterometallic dendrimers containing ferrocenyl-ruthenium(II)-arene motifs: Synthesis, structure, electrochemistry, and preliminary cell proliferation studies

Four first- and second-generation heterometallic ferrocenyl derived p-cymene-Ru(II) metallodendrimers, of general formula [DAB-PPI{(kappa6-p-cymene)Ru((C7H5NO)-2-N,O)PTA(5-ferrocenylvinyl)}n][PF6]n and [DAB-PPI{(kappa6-p-cymene)Ru((C6H5N2)-2-N,N)Cl(5-ferrocenylvinyl)}n][PF6]n (where n = 4 (G1), 8 (G2), DAB = 1,4-diaminobutane, PPI = poly(propyleneimine), PTA = 1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane) have been synthesized. All complexes have been characterized using analytical (i.e., HR-ESI mass spectrometry, HPLC, elemental analysis, and cyclic voltammetry) and spectroscopic (i.e., 1H and 13C{1H} NMR and infrared) methods. Electrochemical studies reveal that the N,O-p-cymene-Ru(II)-PTA complexes result in two irreversible redox processes (oxidation of the Fe(II) and Ru(II) centers), while the N,N-p-cymene-Ru(II) complexes display one reversible wave (Fe(II)/Fe(III) couple). Heterometallic model complexes have been prepared, and for one of the complexes, its molecular structure has been determined by single-crystal X-ray crystallography. In vitro antiproliferation activity of the dendritic ligands and their complexes were evaluated against A2780 and A2780cisR human ovarian cancer lines, the SISO human cervix cancer line, the LCLC-103H human lung cancer line, and the 5637 human bladder cancer line. Nine of the twelve compounds slowed the growth of the ovarian cancer cell lines by more than 50% at equi-iron concentrations of 5 muM.

Mechanism of initiation of the radical chain oxidation by molecular oxygen of hydroxymethylferrocene and its ethyl ether in organic solvents

Autooxidation of ethoxymethylferrocene at 30-50C promoted by the participation of strong and weak carboxylic acids HX is studied. The radical chain mechanism of the process is established, its kinetics characteristics are determined as well as the composition of the products among which other derivatives of ferrocene have been found. Based on the results of the present study and the earlier obtained data on oxidation of hydroxymethylferrocene a mechanism of initiation of the chains general for both metallocomplexes is suggested. It includes the formation of the intermediate CH2OR (R = H, C2H5) and its subsequent oxidative transformations leading to the formation of the peroxide radical C5H 4Fe+?C5H4-CH2O 2 ? and ROH. The role of the approaching and orientation effect in transformations of this intermediate is discussed as well as the mechanism of the investigated reaction in general.
