Hyperspectral dark-field microscopy of human breast lumpectomy samples for tumor margin detection in breast-conserving surgery

May 7, 2024
Author(s)
Jeeseong Hwang, Philip Cheney, Stephen Kanick, Hanh Le, David McClatchy, Helen Zhang, John Lu, Tae Joon Cho, Kimberly Briggman, David W. Allen, Wendy A. Wells, Brian Pogue
Hyperspectral dark-field microscopy (HSDFM) and data cube analysis algorithms demonstrate successful classification of various tissue types, including the detection of carcinoma regions in human post-lumpectomy breast tissues excised during breast

Certification of Standard Reference Material(R) 2196 Axial Resolution Standard for Optical Medical Imaging

February 7, 2023
Author(s)
Jeeseong C. Hwang, Kimberly Briggman, Nikki Rentz, Hyun-Jin Kim, David W. Allen, Lee J. Richter, Sowon Yoon, John Lu
Medical imaging devices and systems must be calibrated to ensure uniformity and reliability of test results. A standard reference material (SRM) or "phantom", as it is known in the medical imaging community, is used to replicate fundamental characteristics

Polydimethylsiloxane tissue-mimicking phantoms with tunable optical properties

July 1, 2022
Author(s)
Aaron Goldfain, Paul Lemaillet, David W. Allen, Kimberly Briggman, Jeeseong C. Hwang
We report on techniques to manufacture and characterize solid tissue-mimicking phantoms of polydimethylsiloxane (PDMS) polymers. Tunability of the absorption (a()) and reduced scattering spectra (s'()) in the wavelength range of 500 nm to 850 nm is

Development and Evaluation of Bluetooth Low-Energy Device for Electronic Encounter Metrics

January 20, 2022
Author(s)
Katy Keenan, Joe Aumentado, Harold Booth, Kimberly Briggman, Mikail Kraft-Molleda, Michele Martin, Rene Peralta, Angela Robinson, Krister Shalm, Michelle Stephens, Emily Townsend, Sae Woo Nam
The coronavirus disease 2019 (COVID-19) pandemic led to the need for tracking of physical contacts and potential exposure to disease. Traditional contact tracing can be augmented by electronic tools called "electronic contact tracing" or "exposure

Dual-comb photoacoustic spectroscopy

June 19, 2020
Author(s)
Jacob T. Friedlein, Esther Baumann, Kimberly Briggman, Gabriel M. Colacion, Fabrizio R. Giorgetta, Daniel I. Herman, Nathan R. Newbury, Jeeseong Hwang, Ian R. Coddington, Kevin C. Cossel, Gabriel Ycas, Christopher Yung, Eli V. Hoenig, Edgar F. Perez, Aaron Goldfain
Spectrally-resolved photoacoustic imaging is a promising technique for label-free imaging in optically scattering materials. However, this technique often requires acquisition of a separate image at each wavelength of interest. This reduces imaging speeds

Nonlinear Silicon waveguides produce tunable frequency combs spanning 2.0-8.5 ?m

September 25, 2019
Author(s)
Nima Nader, Abijith S. Kowligy, Jeffrey T. Chiles, Eric J. Stanton, Henry R. Timmers, Alexander J. Lind, Kimberly Briggman, Scott Diddams, Flavio Caldas da Cruz, Richard Mirin, Sae Woo Nam, Daniel M. Lesko
We present fully air clad suspended-silicon waveguides for efficient nonlinear interactions limited only by the silicon transparency. Novel fork-shaped couplers provide efficient input ( 2 dB) and broadband 3 dB output coupling spanning 6.0-8.5 υm

Polydimethylsiloxane tissue-mimicking phantoms for quantitative optical medical imaging standards

March 24, 2017
Author(s)
Jeeseong Hwang, Hyun J. Kim, Paul Lemaillet, Dirk Grosenick, Thomas Gladytz, David McClatchy III, Kimberly A. Briggman, Brian Pogue
We report on a procedure to build and characterize solid tissue-mimicking phantoms of polydimethylsiloxane (PDMS) polymers. Controlled inclusion of light scattering titanium dioxide (TiO2) nanoparticles enables the creation of phantoms having tunable light

Immobilization of Proteins on Carboxylic Acid-Functionalized Nanopatterns

November 28, 2012
Author(s)
John Peter Ngunjiri, Daniel J. Stark, Tian Tian, Kimberly Briggman, Jayne C. Garno
The immobilization of proteins on nanopatterned surfaces was investigated using in situ atomic force microscopy (AFM) and ex situ infrared reflectance-absorption spectroscopy (IRAS). The AFM-based lithography technique of nanografting provided control of

Trapping and Release of Citrate-Capped Gold Nanoparticles

August 1, 2011
Author(s)
Darwin R. Reyes-Hernandez, Geraldine I. Mijares, Brian J. Nablo, Kimberly A. Briggman, Michael Gaitan
An electrical method to trap and release charged gold nanoparticles on and from the surface of alkanethiol self-assembled-monolayer (SAM) modified gold electrodes is presented. Gold nanoparticle (GNP) coated electrodes were formed by immersing amine
