Preparation and comparison of Fe3O4@graphene oxide nanoclusters for analysis of glimepiride in urine by surface-assisted laser desorption/ionization time-of-flight mass spectrometry
Graphene oxide (GO) has the ability to absorb certain compounds, and it can be modified with functional groups for different purposes; for instance, iron oxide (IO) nanoparticles can be used to concentrate ana...

Copper-induced synthesis of palladium/copper popcorn nanoparticles as sensors for differential pulse voltammetric determination of dopamine
Popcorn nanoparticles (pop-NPs) consisting of a Pd/Cu alloy were synthesized using a seed-mediated growth method. The Cu and Pd atoms were co-deposited on a cubic Pd seed to reduce the energy of fault stacking...

Gold-decorated magnetic nanoparticles modified with hairpin-shaped DNA for fluorometric discrimination of single-base mismatch DNA
The authors describe the use of gold-decorated magnetic nanoparticles (Au/MNPs) in discriminating DNA sequences with a single-base (guanine) mismatch. The Au/MNPs were characterized through dynamic light scatt...

Branched silver nanowires on fluorine-doped tin oxide glass for simultaneous amperometric detection of H2O2 and of 4-aminothiophenol by SERS
This study introduces a two-step method for the deposition of branched silver nanowires (AgNWs) on fluorine-doped tin oxide (FTO) glass. This material serves as both an active surface-enhanced Raman-scattering...

Reducing Spatial Heterogeneity of MALDI Samples with Marangoni Flows During Sample Preparation
This work demonstrates a method to prepare homogeneous distributions of analytes to improve data reproducibility in matrix-assisted laser desorption/ionization (MALDI) mass spectrometry (MS). Natural-air dryin...

Evaluation of adiabatic runaway reaction of methyl ethyl ketone peroxide by DSC and VSP2
Methyl ethyl ketone peroxide (MEKPO) is generally applied to manufacturing in the polymerization processes. Due to thermal instability and high exothermic behaviors of MEKPO, if any operation is undertaken rec...

Detecting small lung tumors in mouse models by refractive-index microradiology
Refractive-index (phase-contrast) radiology was able to detect lung tumors less than 1 mm in live mice. Significant micromorphology differences were observed in the microradiographs between normal, inflamed, a...

Synthesis of 3-O-sulfonated heparan sulfate octasaccharides that inhibit the herpes simplex virus type 1 host–cell interaction
Cell surface carbohydrates play significant roles in a number of biologically important processes. Heparan sulfate, for instance, is a ubiquitously distributed polysulfated polysaccharide that is involved, amo...

Investigations of flow field designs in direct methanol fuel cell
An experimental and simulation research had been performed to investigate the performance as well as the flow distribution in the cathode flow field in the case of direct methanol fuel cells (DMFCs). The gas w...

Structural characterization of sialic acid synthase by electrospray mass spectrometry—A tetrameric enzyme composed of dimeric dimers
Sialic acid synthase (NeuB) encoded by the neuB gene catalyzes the condensation of N-acetylmannosamine and phospho(enol)pyruvate to form N-acetylneuraminic acid. The enzyme is essential for the biosynthesis of...

Plastic Microchip Electrophoresis for Clinical Applications of DNA Analysis
Microfluidic devices were fabricated on poly(methyl methacrylate) (PMMA) substrate using heat embossing method. Results indicated that all of the 11 DNA fragments of the size marker (HaeIII digest of φX174) could...
