The Role of Heating in the Electrochemical Response of Plasmonic Nanostructures under Illumination

The role played by heating in the electrochemical behavior of plasmonic nanostructures under illumination was examined through a combination of theoretical modeling and experimental investigations. A theoretical treatment of heating in plasmonic electrochemical systems was developed, which treats heat flow from arrays of nanoparticles attached to an electrode as a heat source delocalized across the electrode-solution interface. Within this framework, simple analytical expressions for the temperature profile in the vicinity of illuminated electrodes are presented for a 1D model treating heat transfer via conduction. Results from more detailed finite element simulations treating heat transfer via both conduction and convection in realistic cell geometries are also provided. Both approaches predict significant increases in the mass transfer of dissolved redox species, which can readily explain the current enhancements observed with electrodes decorated with plasmonic nanostructures under illumination. These predictions were tested experimentally by employing conventional, millimeter-sized electrodes decorated with Au nanoparticles in potential step experiments under intermittent illumination. Experiments with both outer-sphere (ferrocene methanol) and inner-sphere (hydrazine) redox couples displayed significant current enhancements due to illumination, which agreed well with theoretical predictions. Experiments at individual nanoparticles were also carried out using probe-based techniques. These measurements displayed no significant effects due to heating, attributable to efficient heat transfer away from nanoparticles in this experimental geometry. Implications of these results on research into the effects of hot charge carriers in electrochemical experiments are discussed.

Investigation of the electrochemical behaviour of TiMo alloys in simulated physiological solutions

This paper addresses on the electrochemical behaviour of three TiMo alloys exposed to simulated physiological environments. Their stability and corrosion resistance was characterized in order to explore the potential application for the manufacturing of implant materials. Ringer’s solution together with an acidic modification of the Ringer’s solution (pH 3.1) at room temperature were considered. Both electrochemical methods (namely, potentiodynamic polarization curves and electrochemical impedance spectroscopy, EIS), and spatially resolved scanning electrochemical microscopy (SECM), were used. Additionally, surface characterization was made employing optical microscopy and scanning electron microscopy (SEM). The oxide films formed on the TiMo alloys in neutral and acidic Ringer’s solutions effectively protect the metal from dissolution in these environments, and no breakdown of the passive layer occurs in the potential range up to +1.00 V vs. SCE. SEM micrographs of retrieved samples do not show corrosion pits, cracks, or any other defects despite the rather high positive potential values reached during the potential excursion. EIS data reveal that two-layer oxide films are formed, consisting of a porous outer layer and a compact inner layer (approximately 5-6 nm thick), the latter accounting almost completely for the corrosion resistance of the materials. The corrosion resistance of the inner compact film towards metal dissolution is smaller in the acidic environment, whereas it increases with higher Mo contents in the alloy. The passive oxide films exhibit dielectric characteristics towards charge transfer when they are imaged by scanning electrochemical microscopy.

Ferrocenyl Janus mixed-dendron stars and their stabilization of Au and Ag nanoparticles

Janus molecular architectures have recently attracted attention due to their structures and properties that differ from those of traditional symmetric structures. Herein, two new small redox-reversible mixed-dendron star-shape molecules containing three ferrocenyl groups have been synthesized by linking two distinct dendrons using an esterification reaction. These organometallic nano structures were characterized by 1H and 13C NMR, MS, IR and UV?vis. spectroscopies and cyclic voltammetry confirming the number of ferrocenyl groups and AFM and DLS showing micellar assemblies. Au and Ag nanoparticles were stabilized in the presence of a mixed-dendron structure having amidoferrocene termini upon reaction of the nanoparticle metal precursor with NaBH4. Compared reactions of the two star-molecules with HAuCl4 showed a slow redox reaction leading to Au nanoparticles only with the star-molecule terminated with triazolyferrocene termini, which is taken into account by the difference of their redox potentials.

Non-invasive breast cancer diagnosis through electrochemical biosensing at different molecular levels

The rapid and accurate determination of specific circulating biomarkers at different molecular levels with non- or minimally invasive methods constitutes a major challenge to improve the breast cancer outcomes and life quality of patients. In this field, electrochemical biosensors have demonstrated to be promising alternatives against more complex conventional strategies to perform fast, accurate and on-site determination of circulating biomarkers at low concentrations in minimally treated body fluids. In this article, after discussing briefly the relevance and current challenges associated with the determination of breast cancer circulating biomarkers, an updated overview of the electrochemical affinity biosensing strategies emerged in the last 5 years for this purpose is provided highlighting the great potentiality of these methodologies. After critically discussing the most interesting features of the electrochemical strategies reported so far for the single or multiplexed determination of such biomarkers with demonstrated applicability in liquid biopsy analysis, existing challenges still to be addressed and future directions in this field will be pointed out.

Electrochemically driven catalysis of Rhizobium sp. NT-26 arsenite oxidase with its native electron acceptor cytochrome c552

We describe the catalytic voltammograms of the periplasmic arsenite oxidase (Aio) from the chemolithoautotrophic bacterium Rhizobium sp. str. NT-26 that oxidizes arsenite to arsenate. Electrochemistry of the enzyme was accomplished using its native electron transfer partner, cytochrome c552 (cyt c552), as a mediator. The protein cyt c552 adsorbed on a mercaptoundecanoic acid (MUA) modified Au electrode exhibited a stable, reversible one-electron voltammetric response at + 275 mV vs NHE (pH 6). In the presence of arsenite and Aio the voltammetry of cyt c552 is transformed from a transient response to an amplified sigmoidal (steady state) wave consistent with an electro-catalytic system. Digital simulation was performed using a single set of parameters for all catalytic voltammetries obtained at different sweep rates and various substrate concentrations. The obtained kinetic constants from digital simulation provide new insight into the kinetics of the NT-26 Aio catalytic mechanism.

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.

?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.

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.
