11. Designing High-Performance PbS and PbSe Nanocrystal Electronic Devices through Stepwise, Post-Synthesis, Colloidal Atomic Layer Deposition
Topic: Bioscience & Health
Published: 2/6/2014
Authors: Soong Ju Oh, Nathaniel E. Berry, Hi-Hyuk Choi, E. Ashley Gaulding, Hangfei Lin, Taejong Paik, Benjamin T. Diroll, Shinichiro Muramoto, Murray B. Christopher, Cherie R. Kagan
Abstract: We report a facile, solution based, post synthetic colloidal atomic layer deposition (PS-cALD) process to engineer the surface stoichiometry and therefore electronic properties of lead chalcogenide nanocrystal (NC) thin films. Using the stepwise and ...

12. Si3N4 optomechanical crystals in the resolved-sideband regime
Topic: Bioscience & Health
Published: 1/27/2014
Authors: Marcelo Ishihara Davanco, Serkan Ates, Yuxiang Liu, Kartik A Srinivasan
Abstract: We demonstrate sideband-resolved Si3N4 optomechanical crystals supporting 105 quality factor optical modes at 980 nm, coupled to approximately 4 GHz frequency mechanical modes with quality factors of approximately 3000. Optomechanical electromagneti ...

13. Tunable electrical conductivity in metal-organic framework thin film devices
Topic: Bioscience & Health
Published: 1/3/2014
Authors: Albert A. Talin, Andrea Centrone, Alexandra C. Ford, Michael E Foster, Vitalie Stavila, Paul M Haney, Robert Adam Kinney, Veronika A Szalai, Farid El Gabaly, Heayoung Yoon, Francois Leonard, Mark Allendorf
Abstract: We report a strategy for realizing tunable electrical conductivity in MOFs in which the nanopores are infiltrated with redox-active, conjugated guest molecules. This approach is demonstrated using thin-film devices of the MOF Cu3(BTC)2 (also known as ...

14. Probing the intracellular glutathione redox potential using in-cell NMR spectroscopy
Topic: Bioscience & Health
Published: 1/2/2014
Authors: Steve Y. Rhieu, Aaron A Urbas, Daniel W Bearden, John P Marino, Vytautas Reipa, Katrice A Lippa
Abstract: Non-invasive and real-time analysis of cellular redox processes has been greatly hampered by lack of suitable measurement techniques. Here we describe an in-cell nuclear magnetic resonance (NMR)-based method for measuring the intracellular glutathion ...

16. Effect of interdome spacing on the resonance properties of plasmonic nanodome arrays for label-free optical sensing
Topic: Bioscience & Health
Published: 11/11/2013
Authors: Charles J. Choi, Stephen Semancik
Abstract: In this paper, we report on experimental and theoretical studies of investigating how the structural properties of plasmonic nanodome array devices determine its optical properties and sensing performance. We focused on examining the effect of the i ...

17. Fabrication and Characterization of a Dual-mode SPR/SERS Sensor Based on Plasmonic Nanodome Arrays
Topic: Bioscience & Health
Published: 11/3/2013
Authors: Charles J. Choi, Stephen Semancik
Abstract: This work describes a label-free, optical sensor system fabricated on a flexible plastic film with dual detection modalities: surface-enhanced Raman scattering (SERS) for specific chemical identification and localized surface plasmon resonance (LSPR) ...

18. Airbrushed Nanofiber Scaffolds Support Bone Marrow Stromal Cell Differentiation
Topic: Bioscience & Health
Published: 11/1/2013
Authors: Carl George Simon Jr, Wojtek J Tutak, Sumona Sarkar, Tanya M. Farooque, Jyotsnendu (Jyotsnendu) Giri, Dongbo Wang, Sheng Lin-Gibson, Joachim Kohn, Durgadas Bolikal
Abstract: Nanofiber scaffolds are effective for tissue engineering since they emulate the fibrous nanostructure of native extracellular matrix (ECM). Although electrospinning has been the most common approach for fabricating nanofiber scaffolds, airbrushi ...

19. Determining carbapenemase activity with 18O labeling and targeted mass spectrometry
Topic: Bioscience & Health
Published: 10/16/2013
Authors: Meiyao Wang, Yang Shen, Illarion V Turko, Daniel Nelson, Shuwei Li
Abstract: Carbapenems are broad spectrum antibiotics considered as last resort drugs to treat bacterial infections. Carbapenem-hydrolyzing β-lactamases (also called carbapenemases), however, can confer bacterial resistance and represent a serious health t ...

20. Comprehensive analysis of protein digestion using six trypsins reveals the origin of trypsin as a significant source of variability in proteomics
Topic: Bioscience & Health
Published: 10/11/2013
Authors: Stephen E Stein, Paul A Rudnick, Scott J Walmsley, Qian Dong, Alexey I Nesvizhskii, Yuxue Liang
Abstract: Trypsin is an endoprotease commonly used for sample preparation in proteomics experiments. Importantly, protein digestion is dependent on multiple factors, including the trypsin origin and digestion conditions. In-depth characterization of tryp ...
