Topology and Kinetic Pathways of Colloidosome Assembly and Disassembly

April 11, 2025
Author(s)
Raymond Adkins, Joanna Robaszewski, Seungwoo Shin, Fridtjof Brauns, Leroy Jia, Ayantika Khanra, Prerna Sharma, Robert Pelcovits, Thomas Powers, Zvonimir Dogic
Liquid shells, such as lipid vesicles, emulsions, and soap bubbles, are ubiquitous throughout biology, engineered matter, and everyday life. Their creation or disintegration is defined by a singularity separating topologically distinct one-boundary

JBO Special Issue on Hyperspectral Imaging

March 4, 2025
Author(s)
Baowei Fei, Jeeseong Hwang, Matija Milanic
The editors introduce a Journal of Biomedical Optics (JBO) feature issue on "Hyperspectral imaging." The special issue features a number of important research and review papers on new hyperspectral imaging and detection devices and associated technologies

Engineering Nanopore Approaches toward Protein Sequencing

July 25, 2023
Author(s)
Xiaojun Wei, Tadas Penkauskas, Joseph Reiner, Mark Uline, Qian Wang, Sheng Li, Aleksei Aksimentiev, Joseph Robertson, Chang Liu
Biotechnological innovations have vastly improved the capacity to perform large-scale protein studies, while the methods we have of identifying and quantifying individual proteins are still inadequate to perform protein sequencing at the single-molecule

Microfluidic techniques for mechanical measurements of biological samples

January 20, 2023
Author(s)
Paul Salipante
The use of microfluidics to make mechanical property measurements is increasingly common. Fabrication of microfluidic devices has enabled various types of flow control and sensor integration at micrometer length scales to interrogate biological materials

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

NIST Traveling Tunable Laser Projector (TTLP) for UV-Blue Disinfection Dose Determinations

June 21, 2022
Author(s)
Thomas C. Larason, Steven Grantham, Clarence Zarobila, Yuqin Zong, C Cameron Miller, Michael Schuit, Brian Holland, Stewart Wood, Melissa Krause
As COVID-19 was overtaking the world in the spring of 2020, the National Institute of Standards and Technology began collaborating with the National Biodefense Analysis and Countermeasures Center to study the inactivation of SARS-CoV-2 to different UV and

The Structure of Lipids and Keratin in Adhesive Gecko Setae Determined by NEXAFS Imaging

March 1, 2022
Author(s)
Daniel A. Fischer, Cherno Jaye, Katinka R. Holler, Mette H. Rasmussen, Joe E. Baio, Stanislav N. Gorb, Tobias Weidner
Geckos have the astonishing ability to climb on vertical surfaces due to the adhesive properties of fibrous setae at the tips of their toe pads. While the adhesion mechanism principle, based on van-der-Waals interactions of myriads of spatula located at
