1. Quantitative scheme for full-field polarization rotating fluorescence microscopy (PROM) using a liquid crystal variable retarder
Published: 5/14/2015
Authors: John F. Lesoine, Ji Y. Lee, Hyeong Gon (Hyeonggon) Kang, Matthew Lawrence Clarke, Robert C. Chang, Ralph Nossal, Jeeseong Hwang
Abstract: We introduce real-time, full-field, polarization rotating fluorescence microscopy (PROM) to monitor the absorption dipole orientations of fluorescent molecules. A quarter-wave plate, in combination with a liquid crystal variable retarder (LCVR ...

2. Dimensional Metrology of Lab on a Chip Internal Structures: a Comparison of Optical Coherence Tomography with Coherence Fluorescence Microscopy
Published: 4/8/2015
Authors: Darwin R Reyes-Hernandez, Michael W Halter, Jeeseong Hwang
Abstract: The characterization of internal structures in a polymeric device, specifically of a final product, will require a different set of metrology techniques than those traditionally use in the characterization of microelectronic devices. OCT is relati ...

3. Making digital phantoms with spectral and spatial light modulators for quantitative applications of hyperspectral optical medical imaging devices
Published: 3/6/2015
Authors: Bonghwan B. Chon, fuyuki Tokumasu, Ji Youn Lee, David W Allen, Joseph Paul Rice, Jeeseong Hwang
Abstract: We present a procedure to generate digital phantoms with a hyperspectral image projector (HIP) consisting of two liquid crystal on silicon (LCoS) spatial light modulators (SLMs). The digital phantoms are 3D image data cubes of the spatial distri ...

4. Measurement of the optical properties of solid biomedical phantoms at the National Institute of Standards and Technology
Published: 3/6/2015
Authors: Paul Lemaillet, David W Allen, Jeeseong Hwang
Abstract: Solid phantoms that serve as a proxy for human tissue and provide a convenient test subject for optical medical imaging devices. In order to determine quantitative performance of a given system, the absolute optical properties of the subject mus ...

5. An Average Enumeration Method of Hyperspectral Imaging Data for Quantitative Evaluation of Medical Device Surface Contamination
Published: 9/15/2014
Authors: Hanh Le, Moon Kim, Jeeseong Hwang, Yi Yang, Pawneena U-Thainual, Jin Kang, Do-Hyun Kim
Abstract: We propose a quantification method called Mapped Average Principal component analysis Score (MAPS) to enumerate the contamination coverage on common medical device surfaces. The method was adapted from conventional Principal Component Analysis (P ...

6. A Candidate Reference Analytical Method for Quantification of Low Concentrations of Plasmid DNA by Exhaustive Counting of Single DNA Molecules in a Flow Stream
Published: 8/4/2014
Authors: Hee-Bong Yoo, Dong-Geun Oh, Jae Yong Song, Mamoru Kawaharasaki, Jeeseong Hwang, In Chul Yang, Sang-Ryoul Park
Abstract: This work demonstrates accurate measurement of the concentration of low-level plasmid DNA by counting individual DNA molecules using a high-sensitivity flow cytometric setup. Plasmid DNA is a widely used form of DNA, and its quantity often needs ...

7. Inward cholesterol gradient of the membrane system installed by malaria parasites in normal and sickle erythrocytes
Published: 5/29/2014
Authors: Fuyuki Tokumasu, Georgeta Crivat, Hans Ackerman, Jeeseong Hwang, Thomas E. Wellems
Abstract: Plasmodium falciparum (Pf) infection remodels the human erythrocyte with new membrane systems, including a modified host erythrocyte membrane (EM), a parasitophorous vacuole membrane (PVM), a tubulovesicular network (TVN), and Maurer's clefts (MC ...

8. Single molecule confocal fluorescence lifetime correlation spectroscopy for accurate nanoparticle size determination
Published: 5/15/2014
Authors: Bonghwan B. Chon, Kimberly A Briggman, Jeeseong Hwang
Abstract: We report on an experimental procedure in confocal single molecule fluorescence lifetime correlation spectroscopy (FLCS) to determine the range of excitation power and molecule concentration in solution under which the application of an unmodified ...

9. Optical Coherence Tomography for Dimensional Metrology of Lab-on-a-chip devices
Published: 10/27/2013
Authors: Darwin R Reyes-Hernandez, Michael W Halter, Jeeseong Hwang
Abstract: Here we present a new metrology tool for the determination of the dimensions of channels from final product Lab-on-a-chip devices. Using Optical Coherence Tomography (OCT) areas of up to 12 mm x 12 mm can be imaged in less than 1 second, without the ...

10. Mapping the Vif-A3G interaction using peptide arrays: a basis for anti-HIV lead peptides
Published: 6/15/2013
Authors: Jeeseong Hwang, Ji Y. Lee, Abigail E. Miller, Tali Reingewertz, Elena Britan-Rosich, Shahar Rotem-Bamberger, Mathias Viard, Robert Blumenthal, Assaf Friedler
Abstract: Human apolipoprotein-B mRNA-editing catalytic polypeptide-like 3G (A3G) is a cytidine deaminase that restricts retroviruses, endogenous retro-elements and DNA viruses. A3G plays a key role in the anti- HIV-1 innate cellular immunity. The HIV-1 Vif ...
