  1. UV Photoelectron Spectroscopy at Near Ambient Pressures: Mapping Valence Band Electronic Structure Changes from Cu to CuO.

    Analytical Chemistry (Washington) 86(8):3683 (2014) PMID 24601627

    I photon source in a custom built laboratory ambient pressure photoelectron spectrometer (Lab-APPES). Polycrystalline Cu surfaces were gradually oxidized in O2 to Cu2O, to a mixture of Cu2O + CuO, and finally to CuO between 300 and 625 K and at NAP. Typical VB features for Cu, Cu2O, and CuO were obs...
  2. Ion Fusion of High-Resolution LC-MS-Based Metabolomics Data to Discover More Reliable Biomarkers.

    Analytical Chemistry (Washington) 86(8):3793 (2014) PMID 24611595

    A systematic approach for the fusion of associated ions from a common molecule was developed to generate "one feature for one peak" metabolomics data. This approach guarantees that each molecule is equally selected as a potential biomarker and may largely enhance the chance to obtain reliable findin...
  3. Fabrication of gold nanoparticle-embedded metal-organic framework for highly sensitive surface-enhanced Raman scattering detection.

    Analytical Chemistry (Washington) 86(8):3955 (2014) PMID 24646316

    We discussed the fabrication, physical characterization, and SERS activity of our novel substrates by measuring the Raman signals of a variety of model analytes. The SERS substrate was found to be highly sensitive, robust, and amiable to several different target analytes. A SERS detection limit of 4...
  4. Optimization and simulation of tandem column supercritical fluid chromatography separations using column back pressure as a unique parameter...

    Analytical Chemistry (Washington) 86(8):4033 (2014) PMID 24661124

    We show how tandem column SFC selectivity can be optimized by changing relative dimensions (length or inner diameter) of the coupled columns. Moreover, we apply column back pressure as a unique parameter for SFC optimization. Continuous tuning of tandem column SFC selectivity is illustrated through...
  5. Toward Understanding of Transfer Mechanism between Electrochemiluminescent Dyes and Luminescent Quantum Dots.

    Analytical Chemistry (Washington) 86(8):3939 (2014) PMID 24690085

    We have investigated both electrochemiluminescence (ECL) and photoluminescence (PL) properties of the hybrid system, in which tris(2,2'-bipyridyl)ruthenium(II) ([Ru(bpy)3](2+))/2-(dibutylamino)ethanol (DBAE) and QD are employed as the ECL donor and acceptor, respectively. Unexpectedly, we find that...
  6. Behavior and Determination of Titanium Dioxide Nanoparticles in Nitric Acid and River Water by ICP Spectrometry.

    Analytical Chemistry (Washington) 86(7):3453 (2014) PMID 24575712

    ICP spectrometry (ICPMS, ICPOES) are classical techniques for the determination of solubilized or suspended elements. Unfortunately, their relevance for nanoparticles at low concentration (below 10 ppm) is rarely called into question, even if literature reports are not always coherent. This work is...
  7. Suppression of Apparent Fluid Flow in Capillary Isotachophoresis without Recourse to Capillary Coating.

    Analytical Chemistry (Washington) 86(7):3317 (2014) PMID 24624887

    This manuscript describes a new analytical methodology that allows one to stop the apparent fluid flow in uncoated fused silica capillaries. This method, which requires neither capillary coating nor buffer additive, is based on the use of a 22% polyethylene oxide gel which is placed at the anodic en...
  8. Turn-On Fluorescence Sensor for Intracellular Imaging of Glutathione Using g-C3N4 Nanosheet-MnO2 Sandwich Nanocomposite.

    Analytical Chemistry (Washington) 86(7):3426 (2014) PMID 24655132

    We demonstrate a facile one-step approach for the synthesis of a g-C3N4 nanosheet-MnO2 sandwich nanocomposite for the first time. The fluorescence of g-C3N4 nanosheet in this nanocomposite is quenched, which attributing to fluorescence resonance energy transfer (FRET) from a g-C3N4 nanosheet to the...
  9. Metabolic Analysis of Striatal Tissues from Parkinson's Disease-like Rats by Electrospray Ionization Ion Mobility Mass Spectrometry.

    Analytical Chemistry (Washington) 86(6):3075 (2014) PMID 24548008

    Electrospray ionization ion mobility mass spectrometry (ESI-IMMS) was used to study the striatal metabolomes in a Parkinson's like disease (PD-like) rat model. Striatal tissue samples from Berlin Druckrey IV (BD-IV) with PD-like disease 20 dpn-affected and 15 dpn-affected rats (dpn: days postnatal)...
  10. Small molecule-initiated light-activated semiconducting polymer dots: an integrated nanoplatform for targeted photodynamic therapy and imagi...

    Analytical Chemistry (Washington) 86(6):3092 (2014) PMID 24552272

    We prepared an integrated nanoplatform for targeted PDT and imaging of cancer cells using folic acid and horseradish peroxidase (HRP)-bifunctionalized semiconducting polymer dots (FH-Pdots). In the FH-Pdots, meta-tetra(hydroxyphenyl)-chlorin (m-THPC) was used as photosensitizer to produce cytotoxic...
