Recent advancements in the gas-phase MicroChemLab
Sandia's hand-held MicroChemLab system uses a micromachined preconcentrator, a gas chromatography channel, and a quartz surface acoustic wave array detector for sensitive/selective detection of
Diazonium-functionalized horseradish peroxidase immobilized via addressable electrodeposition: direct electron transfer and electrochemical detection.
TLDR
The direct electrically addressable deposition of diazonium-modified enzymes is examined for electrochemical sensor applications and studies of direct electron transfer of enzymes can benefit from protein electrodes prepared by this method.
Highly ordered tailored three-dimensional hierarchical nano/microporous gold–carbon architectures
The preparation and characterization of three-dimensional hierarchical architectures, consisting of monolithic nanoporous gold or silver films formed on highly ordered 3D microporous carbon supports,
Synthesis and Characterization of Titania-Graphene Nanocomposites.
In this work, the synthesis and physiochemical characterization of titanium oxide nanoparticle−graphene oxide (TiO2−GO) and titanium oxide nanoparticle−reduced graphene oxide (TiO2−RGO) composites
Thermally cleavable surfactants based on furan-maleimide Diels-Alder adducts.
TLDR
Two new surfactant molecules are reported that contain thermally labile Diels-Alder adducts connecting the hydrophilic and hydrophobic sections of each molecule, causing a loss of all surface-active behavior and the micellar aggregates are no longer detectable.
Removable foams based on an epoxy resin incorporating reversible Diels-Alder adducts
We have successfully incorporated Diels–Alder reversible chemistry into epoxy resins. The Diels–Alder chemistry goes in the forward direction at 60 °C and reverses at or above 90 °C. One resin was
Thermally responsive dendrons and dendrimers based on reversible furan-maleimide Diels-Alder adducts.
TLDR
Benzyl aryl ether dendrons and dendrimers containing thermally reversible furan-maleimide Diels-Alder adducts were prepared up to the third generation by 1H NMR.
Selective immobilization of DNA and antibody probes on electrode arrays: simultaneous electrochemical detection of DNA and protein on a single platform.
TLDR
Simultaneous electrochemical detection of a DNA sequence related to the breast cancer BRCA1 gene and the human cytokine protein interleukin-12, which is a substantial component in the immune system response and attack of tumor cells, is reported.
Three dimensional nickel–graphene core–shell electrodes
The annealing of nickel-coated porous carbon structures results in a new three dimensional nanostructured graphene encapsulated nickel core–shell electrode. A highly interdependent and dynamic
