21. Tetracysteine-Based Fluorescent Tags to Study Protein Localization and Trafficking in Plasmodium falciparum-Infected Erythrocytes
Published: 8/10/2011
Authors: Georgeta Crivat, Fuyuki Tokumasu, Juliana Martha Sa , Thomas E. Wellems, Jeeseong Hwang
Abstract: Plasmodium falciparum (Pf) malaria parasites remodel host erythrocytes by placing membranous structures in the host cell cytoplasm and inserting proteins into the surrounding erythrocyte membranes. Dynamic imaging techniques with high spatial and tem ...

22. Real-time polarization microscopy for probing local distributions of biomolecules
Published: 2/28/2011
Authors: Jeeseong Hwang, Ji Y. Lee, John F. Lesoine, Hyeong Gon (Hyeonggon) Kang, Matthew Lawrence Clarke, Robert C. Chang
Abstract: We present real-time, full-field, fluorescence polarization microscopy and its calibration and validation methods to monitor the absorption dipole orientation of fluorescent molecules. A quarter-wave plate, in combination with a liquid crystal varia ...

23. Characterization of Hyperspectral Imaging and Analysis via Microarray Printing of Dyes
Published: 2/22/2011
Authors: Matthew Lawrence Clarke, Maritoni Abatayo Litorja, David W Allen, Daniel Victor Samarov, Jeeseong Hwang
Abstract: The application of hyperspectral imaging requires rigorous characterization of the spatial and spectral imaging domains of the system. We present a microarray printing methodology for the testing of absorption or reflectance microscopy measurements. ...

24. System-independent assessment of OCT axial resolution with a ,bar chartŠ phantom
Published: 2/10/2011
Authors: Robert C. Chang, Jeeseong Hwang, Christopher M Stafford, Anant Agrawal, T. Joshua Pfefer, Megan Connors
Abstract: We present a novel optical phantom approach for the characterization of OCT axial resolution and contrast via multilayered ,bar charts.Š We explored two methods to fabricate these phantoms: the first is based on a combinatorial methods approach from ...

25. Structural Analysis of Soft Multicomponent Nanoparticle Clusters Using Electrospray Differential Mobility Analysis with Transmission Electron Microscopy
Published: 10/22/2010
Authors: Leonard F. Pease , Jeremy Feldblyum, Silvia H. DePaoli Lacaerda, Rajesekhar Anumolu, Peter Yim, Matthew Lawrence Clarke, Hyeong Gon (Hyeonggon) Kang, Jeeseong Hwang
Abstract: Rapid and quantitative techniques are essential to analyze soft multicomponent nanoparticle clusters. Here we combine electrospray differential mobility analysis (ES-DMA), which measures the size of the entire cluster, with transmission electron mic ...

26. Shell and ligand-dependent blinking of CdSe-based core/shell nanocrystals
Published: 7/7/2010
Authors: Bonghwan Chon, Sung Jun Lim, Wonjung Kim, Hyeong Gon (Hyeonggon) Kang, Taiha Joo, Jeeseong Hwang, Seung Koo Shin
Abstract: Blinking of zinc blende CdSe-based core/shell nanocrystals is studied as a function of shell materials and surface ligands. CdSe/ZnS, CdSe/ZnSe/ZnS and CdSe/CdS/ZnS core/shell nanocrystals are prepared by colloidal synthesis and six monolayers of lar ...

27. Monitoring Photothermally Excited Nanoparticles via Multimodal Microscopy
Published: 5/19/2010
Authors: Matthew Lawrence Clarke, Shin G. Chou, Jeeseong Hwang
Abstract: Generation of heat using optically excited nanoparticles can be beneficial or detrimental depending on the application. Therefore, clinically applicable studies are being pursued in an effort to achieve safe practices of nanoparticle-induced hyperth ...

28. Shell-dependent Blinking of CdSe-Based Core/Shell Nanocrystals
Published: 5/10/2010
Authors: Seung Koo Shin, Bonghwan Chon, Sung Jun Lim, Wonjung Kim, Hyeong Gon (Hyeonggon) Kang, Taiha Joo, Jeeseong Hwang
Abstract: Blinking of zinc-blende CdSe-based core/shell nanocrystals are studied as a function of shell materials. CdSe/ZnS, CdSe/ZnSe/ZnS, and CdSe/CdS/ZnS core/shell nanocrystals are prepared by epitaxial growth of two-to-six monolayers (MLs) of shell materi ...

29. Effects of Plasmon-Exciton Coupling on the Optical Properties of CdSe/Zns Quantum Dots Coupled to Gold Nanoparticles
Published: 1/25/2010
Authors: Shin G. Chou, Hyeong Gon (Hyeonggon) Kang, Matthew Lawrence Clarke, Jeeseong Hwang
Abstract: By using a multi-color, multi-modal imaging platform, we look into the effects of exciton-plasmon coupling on a semiconductor quantum dot (QD) that is coupled to a nearby gold nanoparticles (AuNP). By exciting this coupled material with laser excita ...

30. Low-Cost, High-Throughput, Automated Counting of Bacterial Colonies
Published: 1/5/2010
Authors: Matthew Lawrence Clarke, Robert L Burton, A. Nayo Hill, Maritoni Abatayo Litorja, Moon H. Nahm, Jeeseong Hwang
Abstract: Research involving bacterial pathogens often requires enumeration of bacteria colonies. Here we present a low-cost, high-throughput colony counting system consisting of colony counting software and a consumer-grade digital camera or document scanner ...
